External Hardware question

I have 32 channels of i/o with my two Aurora 16’s, but have 16 preamps and 32 channels of hardware outboard effects. So, I can’t have the preamps set up as inputs and all my hardware outboards setup within Cubase’s External Effects in a template. When I use an input for a preamp, that input shows red in my External FX setup.

My question is: When assigning External Effects inputs and outputs, is there a way to hide them, or disable them en masse with one click when using the inputs for preamps? I don’t want to have to unassign inputs to 16 of my External FX when I record and go back and reassign inputs to 16 of External Effects every time I go to mix.

Thanks to anybody with a solution, or who can provide me with some insight into solving this problem!!
