How to control main execution of workflow?

In my workflow, I utilize several metanodes that scrape data from multiple sources. However, there are other parts of the workflow that I intend to execute at a later stage. My concern is that if I run the entire workflow again, it will re-execute the initial metanodes, which take over an hour to complete :weary:, even though I’ve already completed those steps. How can I manage or control this workflow to avoid redundant execution? :thinking:
