It would be really handy if one could associate a Workdrive folder in the Files section of a Bigin deal, contact, or company so that any files put in that Workdrive folder would be quickly accessible through Bigin.

The use case seems like it would be obvious. If there is a "Deal XYZ" folder in Workdrive, and people add files to it, having those show up in Bigin automatically would make sense.
