Lock grid option on perspective filter / perspective adjustment

[rsi.studio]

If the ability to lock the grid was an option with the perspective filter and perspective adjustment, then we could have more functionality in line with image perspective correction. As it is now, the grid follows your movements so it's near on impossible to correct an image with horizontal / vertical distortion with any accuracy, unless you set guides.

 

Better yet, is a lens correction module upgrade in the pipeline?
