Engine Analysis of Multiple Games

Does any software currently exist that can do bulk analysis of a player's database of games and report back on strengths/weaknesses? Single game engine analysis is quite helpful but also quite granular. It just seems like the logical next step beyond that is for a program to take say 50+games (as many as it can handle really) and assess various recurring themes of success/failure. Maybe have batches of games analyzed over rolling 3 month periods (or whatever slice of time you prefer)? Then after building a nice database of such analyses, you ought to be able to isolate and reference periods where, for example, you were playing particularly well in the hope of better understanding a current rut or slump. And of course it could also provide underlying possibilities as to how/why a player has experienced a move in ratings.    

This might make a good freeware/commercial software.

Scid vs. PC can run batch analysis of games, but I don't think any software can assess recurring themes.
