bulk constituent search for Constituency update

Hi all,

I'm looking to bulk add a Constituency for our volunteers. The wrinkle is that I'm not sure which of the 200+ folks are currently in Tessitura. We don't want to create records for their own sake, but recognize those folks who are already in place, and mark them. The order of operations is:

  1. figure out which of the volunteers is already in Tessitura 
  2. mark them with the constituency (if not already marked)
  3. adjust start/end dates as appropriate

Is this possible with vanilla Tessitura? I can enlist Extended Services, but I'd like to know if this is doable without SQL work.
