How to see which stocks a team covers?

Have an up and coming AC for ER at BAML in LDN. I want to prepare for stock pitches but I want to make sure I don't pitch anything they already cover.. I remember it being available on Bloomberg but bit of a hassle to use work computer. In regards to this, I also want to know if I am allowed to pitch something non-European?

I am mostly interested in Tech sector (due to future growth, bit cliche but yeah) and want to pitch in that field, but seeing there are only 27? options in EU when using Finviz, I am a bit discouraged.. What industries have usually "simple" business models?

Also when talking about a sector of interest, I am a bit unsure because e.g. in technology there are so many groups within that I am unsure about how to show interest in a sector?

It is also my first AC/Super Day so super nervous, would love insights/tips if you have any!
