Has there been an update to CRM that allows committee or group members to be added via batch entry?

Recently, functionality was added to CRM to add committee members via selection, which is great. However, it really only is most useful when adding a group of new members who all have the same start date. Existing members cannot be updated and differing start or end dates cannot be added along with the selected PIDs. We have committees where a group of members ends their term at the end of the fiscal year, or maybe we have new historical information to add with a variety of start and end dates.
