Control which fields a Develop user can update in a record in a Roadmaps workspace

Currently when an Aha! Roadmaps record is assigned to a Develop team that gives anyone with contributor permissions in the Develop team access to edit any field on the record (even those in the Roadmaps layout). I'd like a way to control this more to limit Develop teams from updating certain fields that are for PM only. At a minimum I'd like to be able to control whether or not they can set the Develop team field on the Roadmaps record view.
