I would recommend searching for a corresponding wish list for this in the Revit Idea Station, and adding your comments there, or creating a new entry, if there is none already present there yet for the suggested functionality:

Tag it as an API wish:

Ensure it gets as many votes as possible to 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 look there. Your comment here in the discussion forum might be overlooked.
Thank you!
