Prefill more than one designation

In GiveCampus giving forms, available controls depend on your permissions and the interface used by your institution.

A form destination can use numbered parameters such as ?designation_id_1=FIRST_BACKEND_ID&designation_id_2=SECOND_BACKEND_ID with backend identifiers available on that form (not internal numeric GiveCampus IDs). Preserve existing tracking parameters with &. Generate the tracking link to the complete destination and test it. Preselection does not add unavailable designations or restrict the menu to those choices.
