How do tags work in the data wizard?

The Data Wizard imports and update Mailchimp members from a variety of sources. When you reach the last screen, you can assign one or more tags to the records you are importing.

Click add tags. This will allow you to assign any tags that have already been created or create new ones.  The replace option, if checked, will remove any tags to the records you are importing. It will then assign the selected tags you have specified. If you need more granular control of tags, consider our invocable action for tags.
