Simplest way to add single value to stream of rows

What is the simplest way to add for instance a parameter or any value to each row of a stream?

I keep making lookup steps like this:

It creates alot of clutter, specially with the "Add constant" steps which only are used to create a constant "KEY" boolean set to true ('Y') for lookup to do match on.

Preferably I would just like to link "Get_Files_In_Folder" with "Get_Variables" and "Keep_Selected_Fields". But since two of them are input steps, the first is always discarded.

Is there an easier way? With less steps, less code, less clutter?
