Sound Remover - use external input source?

I'm wondering if Sound Remover can use an input sound file to analyze and then remove sound from the main file?

I have file A (vocal mic with drum bleed) and file B (drums).  I'd like to remove or minimize the drums in the vocal mic.  Seems ideal to use the drum mix file to analyze and remove drums from the vocal mic.

I'll try the old school time-align, eq match, inverse mix method and see what I get, but it would be so cool if there was some Audition magic to help.

Thanks for any info!
