The ability to import and export presets from Google Drive (or other cloud storage providers) so as to save physical space on the phone

I have so many presets - paid and free - that I have lost track. I generally always modify them in some way, making even more, and my phone storage has become rather unmanageable. Everything is backed up in Google Drive, so it would be much easier just to keep the original presets on the phone and all the modifications on my Drive.
