This is in my current workflow:

I'm attempting to build a macro to clean this up a little bit. Pictured are 2 of the 19 workflows I am trying to include in a macro (with the same input file and same three tools to the right being linked to all of them). I'm wondering how I can create a macro that condenses all of these tools that will give me the same output and link properly to the union on the right. Is this possible or should I have a macro with all 19 copies of the tools pictured?
