Transferring .scriv. Files directly from scrivener IOS to wireless flash drive

Is there any way to transfer .scriv files directly to my wireless flash drive? I know I can back up the project files to Dropbox (and I do) but I’ve also gotten used to saving the files on my flash drive on my MacBook. Now that I’m using the iPad Pro and have a wireless drive, I’d like to save the files directly there. Need some advice.

You can copy them to the flash drive as a kind of backup, but your iPad Scrivener can’t read from the flash drive.
