Not exactly but maybe I can explain a little better. So, for example. I have 3 projects, each having a primary process flow. Each project's process flow has similar tasks, but the data sets need to be saved to different libraries depending on which project I am running. So, depending on which project I was using, I would set the macro in the first node via a program (similar to your earlier example with the %let statement). Then, ideally, all tasks in that project would save data sets to the library assigned in that macro. In the 2nd and 3rd project, they would have different libraries assigned for their data sets to be saved to. If this worked, none of the actual tasks would ever have to be edited, just the macro for that specific project to point to its library. From your latest example, I could set the default each time I opened a specific project, but I wouldn't be able to automate because EG would default to that library no matter which project I was using.
