Can I import interest labels?

Certainly. You need to insert a column in your Excel file for each interest group. Insert a 0 or an x for any contacts that do not belong to the group, or a 1 for those that do belong to the group. You can replace the number 1 with ascending numbers such as 2, 3, 4, or 5. This allows you to indicate the number of clicks with which the contact is a member of the group.
