I have what I hope is a simple question. I'm trying to setup some macros in a workflow that will just run in successive order, so run the first macro, then run the second and so on. Simple enough but one of my macros ends on a Google BigQuery Output tool, and there's no "output" from that so I don't have a way to add a Macro Output tool to the end. And since it has no output then it can't connect to the next macro in the line. Any suggestions?
