Ability to consider only a Segment or Tag in formulas where MC is the source
A couple of our Mailchimp lists are made up of both subscribers that are in Altru and subscribers that aren't. In addition, since OIC is unable to update organization records in Altru, we find that our Mailchimp-to-Altru formulas often contain records that can't possibly have a match in Altru. Therefore, it would be nice to be able to configure those formulas to consider only those Mailchimp subscribers with a specific Tag or that are in a specific Segment of the source Mailchimp list. We could then make sure that the Segment or Tag contains only those subscribers that could possibly have a matching Altru record.
