Great Idea!! This option will allow you alsow to prove how specific players interact with denses whose stats you know. I mean, if you want to prove how the inside shooting of your PG works in look inside tactic againts a defender without inside defense you just have to alineate as the rival team one of your players with no inside defense. It will help to study how your players work in diferent known situations. I think it could be an useful tool.
