Another idea that is closely related to the memorial screen but slightly different concept is Battle Honours on a Flag or Standard. I suspect this idea is probably suggested before else well. I thought I will write it again to get it out of my system (sorry for suggesting the same idea)
Basically Battle Honours in real life military units show them where they fought. So I think all the statistics of win/loss, how many different monsters killed in each battle and which battle brother died can be there.
