Improving Tactics Trainer

I've been using Tactics Trainer for several months now, and really like it.  Recently I upgraded from Gold to Platinum (primarily for Chess Mentor), but I want to continue to do 25 tactics problems per day (or advance it to 30 or 40 perhaps).  Is there any way of doing that short of manually counting the puzzles?  I'd love to have a setting that allows me to set a number of problems per day, at which point the software would 'warn' me that I'd completed my 25.  Doing the same number every day helps me track my progress and (hopefully) improvement.

I also just discovered the 'Performance' graphs in TT.  Could you add check boxes that a user could select to 'focus' on that/those areas?  In performance, I show in the 90s on a number of areas, but below 20% on a few - and I'd like to be able to have the software emphasize those areas by giving me more problems in those areas (but not to the exclusion of other areas).  Could this be done?

Thanks - I really like the Chess.com web site and hope to use it to improve my chess.
