There might be a work-around: 1. Find your presets (from the preferences dialog) eg.in WIndows- C:\Users\Your Name\AppData\Roaming\Adobe\Lightroom\Develop Presets 2. Close Lr and in Explorer/Finder, Select a preset and make a copy in the same folder. 3. Now restart Lr, develop a 'new' or clean photo that has no developing or has been reset- 4. Apply the 'original' preset to the photo, 5. change the sliders (parameters), now right-click on the 'Copy' preset and "Update with current settings"
"check all", "check none" does not even appear. The copy preset has your slider parameters as you altered them from the original.
