Hi,
I know this is not the solution we are looking for; however, the quickest way I have found to find that "perfect" part is to use the Audition button in the Stylepicker window.

I believe you can mute parts before going into Stylepicker (I don't have access to my BIAB right now so cannot verify this).

With this work around I can generally move fairly quickly through styles and then create my hybrid.

Hope this helps while we await the solution from PG.
