Need help with set simulate physics or respawn issue

First I want to say how helpful the community has been and I have a new issue. Hopefully one of you smart people can help me with my latest challenge. I am making a bowling game and I have run into a bit of an issue. I am simulating a real pin reset mechanism. To do this I am attaching the pins to the reset device. The problem I am having is after I get the pins to attach using attach to actor the pins lose their physics. I was able to do set static mesh if I use the names of the pins individually but I can’t do it in an array such as get all actors with tag, etc.

My first question, how can I use an array to set simulate physics?

My other option is setting the pins individually. The problem I have there is when I have to spawn new pins. I can’t use them by name since they are named when they are spawned. So how can I reference these new spawned pins? I need a way to create a reference to the new spawned ones.

Thanks again for the awesome support.
