Exporting backup to local file system as another option than sharing menu

[krwow]

Hi. Could an option to make backup locally on device be added? Now after choosing "Export full backup" sharing menu opens and there's no way to save file on device. I prefer such option as I can transfer such file to PC, without using any cloud service. For now I use Shoyo app, but that's just a workaround. It would be great if I didn't have to use additional app just for this one case. I believe it can be done without too much work, as it is usually available in the other apps.
