Choosing inputs system-wide

[Saltfred]

Hello!
I'm using an AudioFuse Studio on MacOS 12 and am wondering if there is anyway to select which inputs are used by the system (for example which inputs Discord use). Almost every program i use only detect inputs 1+2, while inputs 3-8 are ignored. Is there any way to change the routing or so to for example make Discord use a mic plugged into input 5?

I am no expert on this but I think there is no way to choose which input is used by the system
