[Android] Chagne default library location to SD card

I see where I can change the locations for each individual file type. I don't want to have to change the locations for each of a couple of dozen file types. I just want my entire library in a folder called "Calibre" on my SD card Is there a way to just set the default library location to my SD card?

I am running Calibre Companion on a Samsung Galaxy Tab A.

Thanks.
