Organize & Delete Lightroom Presets (Cloud Version)

Hi everyone!

I have a problem. After decades of using Photoshop I finally got into Lightroom (cloud version) and downloaded a bunch of presets (1500+). When I imported them, they cam in completely unorganised and the group structure is now a mess. Most of them landed in the "user presets" folder, others got their own folder, but it's generally impossible to find anything now.

Is there any way to organise them? I know I can manage the presets in Lightroom, but since every group contains multiple sets, this solution doesn't work for me. I also don't want to outright delete some groups because just cause they're unsuitable for one photo doesn't mean they're generally useless. Ideally I would want every set in its own group. I also don't have the option of showing them in Folder cause it's the cloud version. I'm on Mac.

Any help appreciated!
