Multiple revs in the configurator

Does anyone know how I can set up mutiple revisions in a single
configurator2 We have one configurator just for our chair line, and
from it you can create about 2 dozen different models of chairs. The
problem is if engineering makes a revision change to one model of
chair, then if we update the revision on our configurable chair part
all models of chairs will show a new revision.

The only solution I found is to put the revision number in the
description of the chair and leave the actual revision number alone.
