Just to sum up what I've learned by trial and error about this post of mine.
Maybe it will help someone in the future.

1. To manually insert drum notes into the Piano Roll that will export to the final .wav file..... you must allow BIAB to generate the drum track FIRST! Then go in and move those GENERATED NOTES around wherever you want them.Use COPY & PASTE with these GENERATED NOTES throughout the tune.
You can use the Shift+Control+Left Click to enter notes manually. You will hear these notes during playback while in BIAB. But these manually entered notes WILL NOT be recorded to the final .wav file.

2.You can Freeze & Save the file anytime AFTER you allow BIAB to generate the track first.

3.Be sure to leave yourself some of the random notes generated in case you need them.
