My goal: Offer the oportunity to extend the given options of a collection_select with custom text within a form

My problem: The collection's ressource is the same the form data will be saved to, so I cannot update the corresponding collection prior to submitting the form as a whole.

Has anyone a smart and simple solution to that?
