Relative to Manual

Can we have the ability to choose that for manual setting. From what I understand about the behaviour of the auto parameter is it updates dynamically, so it would be good to have the same ability with one’s own setting.

I would like this feature.
A mix would be better: The ability to choose per slider.
For each slider you could pick if it’s: manual, relative to auto, relative to manual or full auto.

To be clear, what would relative to manual mean exactly? Would it be a threshold, like if I set 50 on a slider, it can only vary by about plus or minus 10?
The only other way for it to make sense is maybe a hard offset. If I set 50, and auto would choose 24, it end up as 74. That seems a little less useful than the percentage offset it does now.

The main thing that stops me from using Relative to Auto is that I cannot force the Anti-alias/Deblur slider to be ignored or at a set value.
