Sorry I am new to Freeflow core and my company is just starting to transition over from process manager.
I will be on here a lot asking questions.
I am trying to create a workflow using the routing presets, but when I go to create them, under routing rules there is a job characteristic that says "All other Jobs." Is there a way to remove this or modify it so it does not show up as a second or third branch, depending on the workflow?
