An informal question for the experienced users.

Has there ever been a suggestion put forwards for SW to improve the mesh control tool? I'm thinking it would be very handy to be able to 'dynamically' sketch control areas on the model (rather than creating split surfaces). These sketched areas would only exist in the assembly (or in that particular simulation).

I imagine the above tool would be extremely hard to implement, but I'm curious to know if anything like this has been suggested.
