Prevent inheritance for some right click options at product or vendor-level

Today it is possible to set right click options at the All Products level and create overrides at the product or vendor level.

If a product or vendor level change was made to e.g. Manage assignments, and then made a change to the same right click option at the All Products level, inheritance will re-apply down the tree and clobber all previously (and carefully) set vendor or product customisations.

This request is to add a control which allows a user to prevent a product or vendor to be clobbered from inherited settings.
