I've created a Behavior that transforms a text field in to dropdown list search field. That data comes from an external REST service via a Scriptrunner REST endpoint.

I thought that was 'job done' and got back to my day job. However, pesky users have said that the field still appears as simple text field when they update it from Structure, and that it doesn't allow them to search.
Is it possible to apply a Behaviour to a field that appears in Structure?
Or I could use another ScriptRunner function to periodically add new items to a Single Select?
