I just tried to replicate your problem and yes, it doesn't transfer the drum intro.

To overcome this I saved in BIAB the drum track only to a WAV file, followed by a full save as .SGU.

I then opened the SGU in RB and IMPORTED the drum wavefile into RB, muted the original drum track and

hey presto...a song with a drum intro.

It may need some tweeking, but hey it works.

Hope this is of some help.
