Yes. Just create an array of actors. I would use a single actor as the parent and create the items from that parent. Then you can store an array of the item parent and since all the items are children of it, they can be stored there.
EDIT…
For clarification, the array should be of object class reference (the purple option) for easy spawning.
In your actor create a variable and in the variable type selection write in the name of your actor and choose the reference type.
They don’t exist until you spawn them.
I would just use UObjects for the menu.
