Can you do this: Settings>backup/restore>backup library>select a backup destination>[horizontal scroll the path line at the top of the page to the right, select storage]>extsdcard [or equivalent]>android>data>com.zubersoft.mobilesheets>files>then make a new folder[in the overflow, 3 dots, top right]? I would think you could back up to that folder if you can make the folder in the first place.
