Well here’s an example of a free muler from another client and how it works: you first run the script itself, set some settings like what the slave or mule should trade over upon each collection, and once you’ve finished setting it up, it allows you to then from there run another script on top of it which , when it comes time to mule, it then proceeds to pause, I guess in a similar fashion to how OSB pauses scripts to go on a break.
