Description
It makes sense that pipe_input doesn't restrict to the first parameters #1161 and #1173 address this.
Is your feature request related to a problem? Please describe.
Sometimes it would be good to have the flexibility to target multiple parameters with different transforms on a local level like mutate/pipe_output do.
Describe the solution you'd like
Something like step.on_input("target_param")
Describe alternatives you've considered
Using pipe_output on th eprevious node instead of pipe_input. Stacking multiple pipe_input decorators.
Additional context
The scaffolding for this functionality is already implemented, but is disabled / needs to be tested.
