I know right now there is the REVENGE when you re-engage a troop that you lost to (most of the time from Defending) however I would like to have a tally when I re-engage someone again that I have beaten or beat me in PVP – I started tracking manually how many times I encounter the same team (and now my mistakes if I loose) but it would be nice to know that you have faced this opponent before and they have either won or loss x times against you.
