There can only be one profile data per CAD event. This is to prevent duplicate data entry.
Rather than attach the Profile data to the CAD event, the same Profile Data can be entered into a Citation or a Field Interview within a Master Name.
For example:
Two separate contacts could include two Field Interview records with the two Profile Data records attached correspondingly. This will track the contacts in relation to each person rather than having multiple attached to a single entity in ARMS.
