We have an import file from a third party.  The first step is to add new constituents, then we want to add an interaction to record the contact made.  Unfortunately the interaction import process requires a constituent lookup ID - this has only just been created in the first step and isn't in the import file.  Currently we need to export the list, marry the values in the csv file and then run the interaction import.

If I use the same search list myself, I can find the constituent based on alternate lookup IDs, but the import process can't.
