More Than One Enemy Won't Duplicate

This is where I’m lost. The “Set Timer by Function Name” nodes has the “Begin Play” node attached which is why I didn’t duplicate that. I DID miss the function name part and I’m clueless how to put all other spawn actor nodes behind “Spawn Stalker”.
The method I was thinking, attaching them horizontally, still doesn’t change the “By Function Name” part.

I know with materials, I can add constants that will let me add multiple nodes to 1 pin. Haven’t found the equivalent in BP yet.

And you do know that there is very limited information on what the nodes actually do or their properties. Me and my coworker have been looking. Bought a book, but it’s basically the book form of the initial video I linked to. If you have some valid resources, we would appreciate the info.
