PE Fund tracking/accounting model

Does anyone have an example fund accounting/administration excel model that a PE CFO may use to track their portfolio? I realize that this is proprietary so may be hard to find, but was hoping someone had something even if it had dummy numbers in it.

Basically, I want to know how professional PE Fund CFOs track their funds on a deal level. How do they model IRRs by deal, project exits and return multiples etc. I also just want an understanding a CFO tracks. I think seeing how the pros do it will help me understand how to do this at their level.

I'm interested in doing this professionally rather than being on the investment team so learning from someone with experience would help me out a ton. Thanks everyone.
