Locking control knobs to current setting

[norfolkmastering]

I'm trying to find a way to lock my track input gains in their current set positions. 

Once I'm finishing doing the bulk of the recording for a project and getting into mixdown, I set the track input gains to a sensible position so that the levels being fed to inserts and FX are sensible.  This is particular important for me as I use mostly analogue FX.

It's just to stop me accidentally changing an input gain, or maybe because I need to experiment and then go back to the previous setting.

It would be great if I could simply right click on a control and a lock to current position option was available.

Has this ever been considered?  Is there any work-a-round?

Create a new track view widget preset that hides the input gain?
