Join on sidhistory attribute

Is there an easy way to join on the sidhistory attribute?

I'm using ADMT to consolidate forests, and migrating the users with sidhistory.

Both forests are FIM connectors.  I'm importing the objectsid from the source forest into the metaverse, and would like to have a join rule that matches any 1 of several sids in the sidhistory attribute of the target forest.   Is that possible?
