Global Material Override control

[AsOne]

I would love to see a Global Material Override option in the Project Rendering Options in the Display Options palette.

This option would turn off material overrides for all layers.  Yes I know I can implement a Layer Groups or multiple levels of groups.  However sometimes I individually set colors to work with and also make photoshop selections.  To turn them all on at once is tedious.  I know I can use Vray to get a material id output for photoshop, but this requires more work.  A Global Material Override option would improve my workflow.  

To be clear:  this would be an option, similar to Unlock Groups perhaps, that would allow or disallow Material Overrides in the Layers palette.  

Thanks for considering.  

For example:

While working in shaded full I see this:

 

However, at times I want to just see things as a bunch of colors to make modeling easier and also then in Photoshop it makes creating selection sets a lot easier.  I use Layer overrides to achieve this:

 

If there is a way to do this currently - please let me know.

If anyone finds this:  I realized if I put all the layers in a "master" group I can control the settings easily through layer overrides.

My previous comments doesn't really work.  Even with a layer group I would still have to set multiple layer overrides and turn them on/off individually for each layer/color desired.  A global setting would be really handy.

Alternatively some indication in the Layers palette that the layer has an override on would be nice.   button or the layer text is a different color.
