Importing a list based on RE Legacy IDs

Hi everyone,

We converted to Tessitura from Raiser's Edge 7 about a year ago, and I realized that we missed mapping over a handful of solicitor assignments (which we mapped to Attributes in Tessitura). I have a list of constituents' RE Legacy IDs (which is also an attribute in Tessitura). Is there a way to get these folks on a List Manager list so that I can use the Manage Attributes utility to add the info I need?

Thanks so much!
