I would like to assign multiple roles to event participants through imports. I can upload a csv to assign a user role, but if I import a second data source with a different role, it is set aside as a duplicate and not imported. I would like the second role to be added to the existing record. (not overwrite)
For instance I have a list of auction event particapants who are attendees, donors and/or buyers. My lists have overlapping contacts. I would like to keep these all associated with the event, rather than creating groups or tags. Handling the overlaps manually is not practical.
