Add more fields in Administration that can be automatically mapped

I recently had a customer give me feedback about how it would make his life easier if it were possible to automatically configure more fields besides just CSM on the Administration page (screenshot below for reference). 

Has adding more objects here ever been under consideration (I searched previous posts on Community and came up empty), or is there a reason we only have CSM as a configurable option there that I'm not thinking of?

Thanks for your input!
