Make Integration fields from epic card searchable

We have a field on our epic cards called Integrations. It lists the ID# of the epid in ADO that our Epic in Aha is tied to. When I type a services id into my search field I do not find any results. If this were a searchable field in Aha I would have the ability to only need 1 ID# to find the epic in both systems saving time when auditing and prepared for new fiscal years.
