How to add a snap that does nothing.

Hello,

I would like to add a snap (or multiple) which do nothing, and are just for making the pipeline 'more readable'.
This is so that i don't have the x25 -> x25 output-input connections.

I tried to use the mapper snap with 'pass through' on and with no input. But that doesnt work.
Is my only option to select all fields from the mapper input and put the same output and check pass through?

What i tried so far:

As you can see, the '==PASS==' (a mapper) is turning red on validation.

Thanks in advance.
