A.  Yes, there is a feature that allows the set up and configuration of a multi-selection checkbox as a field in the contact record.  This feature allows the user to check more than one option in the drop down of available options on the contact record.

This feature is available for use however, we strongly urge you to contact the help desk prior to implementing on a field already in use.  Changes made to an in-use database in the fields/categories section can result in data loss.  Requires Administrative access, to view more on fields, locate the Administrator section of the knowledge base.
