This feature allows a Site Administrator to add a Program-specific Custom Attribute created in another Program to the Program they’re currently in.
Simply choose from the list and click Add this Custom Attribute and click "OK" on the prompt: "Are you sure you want to add this Custom Attribute to Your Program?"
Note: The added Attribute is not linked to the original attribute with the same name and data entered in those two (or more) attributes will not aggregate in reports.
