Able to link two EX2100's?

I currently use two EX2100’s. One for my file storage/media server and the other for a backup.

I plan to upgrade my primary nas to a 4 bay model soon. Is there a way to link my two existing EX2100’s together so when I do a backup of my new nas it will look at them as one large device? Or will I have to choose to backup half of my 4 bay nas to one ex2100 and the other half to the second ex2100? Thank you
