Multiple input tool that only accepts one active input

[Number4]

I have a workflow that accepts 4 different sets of inputs.

It also has four different outputs.  However, I can easily output to separate files in four containers and just close the containers that don't pertain to the input.

On the input side, I keep having to delete the connections and connect the desired input.

I would like to connect multiple files to one tool and have the tool only work if only one of the inputs it's live.  Through the use of containers you would then choose which input was live.
