Spawn Uniquely to Ones Spawn Box

I have a spawn box that spawns well boxes actually. It works sufficiently enough. If I clone it though it will first spawn them right then after they die it will spawn them both at the first placed box. I have been trying figure out how to make the spawn at their respective boxes but no luck. What is a good method for this? I tried arrays and selecting them with an eye dropper to no avail, same with just actors and eye drop selecting. I know what needs to be done is for each portal to have its own unique ID and then when one is free it spawns an actor. However, with a clone you cannot just say is overlapping spawn box spawn elsewhere. So what is a suggestion for this?

Can you show your BP for spawning and setting the spawn location?
