Make it easier to add multiple repositories

Adding repositories using QR codes is a great feature, but when you have to set up several phones and add all the repositories one by one, it's a bit tedious.

I often configure devices for my friends and family, and when I have to add repositories in F-Droid (I have more than a dozen), it becomes a bit tedious to scan the different QR codes more than 10 times.

Wouldn't it be possible to add them all at once?

For example, by generating a QR code with all the repositories on device A, and when you scan this QR code with device B, all the repositories are added at once?
