Commodities - Struggling to get into a real commercial role. Do I need to be doing more, or is my shop not really set up for this?

Made a similar post a little while ago, and deleted cause I didn't protect my details enough. Here again. 

I have about 5 years experience in my commodity. I'm currently at a trade shop (not as big as Vitol/Traf/Glencore). It's not a very technical commodity. I have a little bit of commercial experience, and have really good scheduling skills + understand the MO and BO stuff. I know I'm capable enough, but commercial value generation roles can be fickle as hell. 

I'm still fairly young in the grand scheme of things, and know commodities can be a long-ish game. 

The set up @ my shop is more so that my trader(s) set up this book, and they have a rough % of book type arrangement with the parent. So I don't really work for the parent at all. 

My job is more senior than day-to-day scheduling people, but below the traders running a book. So more so like an 'optimization specialist.' It's a fairly well paying, low stress job. 

Basically, the problem is I feel pretty bored in my role, and know I can be doing a lot more. But I'm not sure what I should really do. 

My trader straight up offered to give me a legit junior trading role, where that would be my sole focus (but I'd have to make PnL). They told me to think about it for a while, and then I came back a week later, and said I want that. They basically reneged on that, which is shitty, but I have no control over. I am quite sure this is because someone from our parent vetoed it due to having to back fill my role, or me not having an existing trade book. 

Since then, my boss says they are supportive of me having a hybrid commercial role with what I have now. They support me going out to visit customers (and expensing it, of course), and let me handle one or two accounts I helped bring in. They are telling me I need to be more of a self starter if I want to trade, etc. I do have a slightly passive personality, which I need to overcome. 

I feel like there are some pretty big structural obstacles though

• I don't even have a DOA, nor do I really have the support to take out a position. It's not like it's common now to bring in back-to-back deals. Granted, I'd get this support if I was bringing in bacon. 
• My market/industry basically has the same players it always had. We already have people covering these relationships, so I'd basically be handling any fringe accounts.  Which is fine, but then I basically have to rely on another trader to buy/sell the product for my deal. Also, I will be very out of the loop on market information. 
• I'm just out of the loop, and it's not like I get invited to all many lunches with existing commercial counterparts, etc. I'm not saying I have a reason to be, but anything I bring in (and get recognized/paid for) would have to be pretty outside our existing wheelhouse.

I'm not trying to bitch and complain about my situation, even though it may sound like that. But, I've become a little jaded. Stuff like having a possible deal, and then nobody is around to help me move the product. Or, nobody reading my "research." Again, they have their own PnL to worry about, so not complaining. 

But should I really focus on being a trader here, and just asserting myself way more, and actively asking/demanding for people to help me out and include me more? 

Or is my company basically just giving me lip service to make it seem like I can become a trader, when it's not really in the cards?
