Been there with you on this...

You could try making the RealDrum track without the pushes using BIAB, make it an audio file, and then disable the RealDrum track so that the 'unpushed' RD audio plays along with the other instrument pushes. If you want the pushes in the drums, you could make a Midi drum track. Copy it to the Soloist and then edit out (using piano roll editor) everything but the pushes. I don't know how the blend will be using Midi and RD but maybe it's worth trying.

You could also try different RDs. Some seem to work better with pushes than others.
