[Feature request] Split data between drives

[aaronduce]

Havent found a way to do this as of yet in the program, so making the assumption it's not yet possible. I use externals for backups and would like a way where i can fill a drive, and when it is full unplug it into cold storage and plug another one in to fill. That would be very useful for me and I think many others, as it would be very difficult and inconvenient to do something such as a RAID of external drives.

Just create multiple pairs and include only a section of folders, or exclude everything but a section of folders, whatever is easier.
