Is there a way to designate multiple tags with a large import of new People records? For example, I'm importing data from another system that looks like this:

John Smith - tags include A, D, X
Mary Jones - tags include A, B, C, L, S, W
Mike Miller - tags include A, B, D, O, R

I know how to create or import multiple tags, but if every person in the import has a different set of tags associated with them, how can I import those with the proper records without manually tagging each person record after the import? Is this possible?
