How to stop iterate scenario, without re-running "Apify - Run an Actor"

I am building out a scenario, and continuously iterating. The scenario pulls reels from a group of pages, and uploads them to a folder.

Step 1: Run an actor on Apify. It produces 643 bundles.

Step 2: Get Dataset items

Step 3: Add a row

Step 4: Sleep

Step 5: Get a file

Step 6: Upload a file (Filtered by the Like Count from the dataset)

Now, what I would like to do is to add a create a completion module to summarize what’s going on in the reel I scraped.

And then add a row to my sheet.

My question is how do I add these iterations, without having the run the scenario from beginning to end. Trying to save apify credits.

Also, is there a way to program the “run an actor” so it’s only pulling “NEW” reels.
