Link Container Field to Radio Button?
When a user "Inserts File" as a reference into the Container field, I would like an associated radio button to automatically be selected.
Is this possible? (and how?)
My reasoning is that I can't search/sort by Container fields, and so this would provide a searchable/sortable field. If you know of a way to search/sort by whether there is an item in the container field or not, that will also solve the proble.
