A rig-specific "Key"/unlock/lock-override setting to override a global lock setting.
Example
I have my stereo effects loop on in the X position always locked on
I always lock both the reverb and delay to "OFF"
I run a Strymon Mobius, Timeline and Flint in my stereo effects loop (yep... awesome)
The Strymons give me ton ton of tones/versatility, however let's say that I download someone's rig that I like who set it up with effects that I like in X and/or Mod along with a sweet Reverb and Delay. I want to keep my lock settings on a Global basis but I would love to be able to do a rig-specific override by using a key against that lock so that I can save on that specific rig what I want to unlock.
