Is this a programming request, or a request for general Revit functionality?
Please note that this discussion forum is dedicated to programming Revit using the Revit API.
However, in either case, you could submit a wish for this functionality to the Revit Idea Station. Whenever you require a new or enhanced Revit product or Revit API functionality, the Revit Idea Station is the place to go. Please search there for a corresponding wish list entry for the suggested functionality and add your comments to it, or create a new one, if none already exists:

If it is for the API, tag it as an API wish:

Ensuring that a wish gets as many votes as possible helps underline its importance to you and the rest of the developer community. The Revit Idea Station is currently one of the main driving input forces for Revit API enhancements. The Revit development team looks there. Your comment here in the discussion forum might be overlooked. Thank you!
