Hi, I have an urgent problem:
I have to import contact data from different sources. If a contact already exists, fields from the newly imported source will override the existing values of all fields, which are in the new source.
This is fine for most fields. BUT ...
I want to merge all tags from all imported sources.
So, if a contact already has tags from the first source I don't want them to be overridden by the second source. Instead I want to have a complete unique list of all tags from all sources.
Is this possible???
