This is a LEGACY FEATURE and has since been replaced with PROGRAM GROUPS. This feature is not typically actively used by ETO Administrators anymore.
This feature allowed a Site Administrator to add a Program-specific Custom Demographic created in another Program to the Program they were in, which can be handled more effectively using Program Groups.
If you do wish to use this feature, simply choose from the list and click Add this Custom Demographic and it will exist in the Program you’re in.
Note: The added demographic is not linked to the original demographic with the same name and data entered in the 2 (or more) demographics will not aggregate in reports. A Query can be built with the Query Wizard using the focus area Custom Demographics by Name to aggregate demographics created using this feature.
