More than two designations in a URL

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

Use distinct numbered keys such as designation_id_1=ID1&designation_id_2=ID2&designation_id_3=ID3 rather than repeating the scalar designation_id key. Repeated same-name scalar arguments do not produce independent selections in this interface. Each ID must resolve on the target form; selection is capped by the form's maximum designation count. Test in a fresh session because retained selections precede URL defaults. Do not assume five URL values override a two-designation form maximum.
