Is there a way
The Preset panel no longer 'mirrors' the folder structure in Win-10
But a free plug-in to re-arrange presets might be useful to you. Fix Presets Lightroom Plugin
I might try making a copy of the presets folder; rename and restructure from within there and then try importing them as new presets.
What could possibly go wrong? ;-)
I will store the presets in the catalogue, and backup before I make any changes, just to be on the safe side.
Yes, you could re-import presets, BUT the Group they occupy in the Preset panel is dependent on an internal name within the Preset file text, and NOT any folder structure in Win-10.
So good luck, but I do not think you will achieve what you desire!
