Multiple input to single output converter and vice versa

First question so please forgive any mistakes.

I'm trying to design a system by which multiple LEDs are controlled by multiple switches, but without using as many wires as there are switch/LED pairs. I'm planning to have roughly 20 momentary switches connected to the same number of set-reset latches which control LEDs.

I'd like to know if there are any chips or circuits I can use in order to take these 20 inputs, compress them down into as few wires as possible so that I don't have to cable manage 20 wires (which, for my application, will be unfeasible), then provide the same number of outputs at the other end. The outputs will only need to provide a brief pulse along the correct line, due to the set-reset latches I'm using, and no two inputs will be able to be activated simultaneously.

Thanks all.
