Reamping help

[SeventhSounding]

I recently bought a Torpedo Live digital load box and a behringer U-Phoria UMC1820 interface, and want to start recording DI tracks that can be sent through a Pro-RMP studio reamper by radial engineering, and I am unsure how to setup things in a pro tools session in order to Reamp my DI tracks.
Also I wanted to know since I will be building a desk soon for my racked equipment if there is a speaker cable extension for an 8 ohm input to be used with my torpedo live when switching from recording my bass amp and guitar amp. I want to know if I'm just going to need to put up with going all the way to the back of my desk and switch the cables every time or if there is a switcher for 2 heads to be switched to the same cab to take away from this problem.
Thanks for the help, any is greatly appreciated!
