Ability to Edit Template Field on Project

Our PMs would like to have the ability to edit the Template field on a project. Sometimes they need to switch out the template that's used via the Attach Template feature (because they don't have permission to delete the project and re-create it with a new template); however, the project relationship doesn't reflect this. This causes inaccurate reporting in some cases - when the project duration is compared to the template duration, for example.
