Please restore the ability to have subfolders on SD cards

I have an original Ender 3, and just got an S1 Pro. The original Ender 3 could read subfolders (and sub-subfolders) on an SD card. The touchscreen interface on the S1 can see only files in the base directory … and only the first 20 of them. This seems like a huge regression to me, and I can’t imagine any justifiable reason for it.

Please fix, thanks.
