Something that gets brought up once in awhile that would be a nice feature but will likely not happen due to the track limits. That being said if you are looking to get a bit more EQ control in your DAW you can try the following.

Make duplicate copies of the rendered BIAB WAV in your DAW. Leave the original untouched but hard EQ the rest to accentuate what you want. Need more kick drum drop off all the mid to high frequencies and boost the low. You can do this for the part of the kit you want boost or reduce. The problem is it can be tedious task to get the balance right and sometimes will do more harm than good. Sometimes it works great and other times it don't.

The great thing is that the REALDRUMS as recorded are pretty good already and most times you can bring them to life with a few EQ moves and a compressor.
