The iPadOS version cannot support changing the storage location unfortunately, due to the way the operating system works. Applications can not manage files outside of their "sandbox". So all files that MobileSheets wants persistent access to have to be placed under the MobileSheets folder. You can, however, manage the subdirectories under that folder and if you import files from subdirectories inside the MobileSheets folder, the file should be used from that location.
