What is this system called? I want to store item, click item to select actor

It sounds more like I need to check into subsystems.

Basically what I’m doing in my game is very software based. So in my UI I have a list to my right and this list needs to automatically populate with the actors I spawn at runtime. These objects hold data like descriptions and things.

It’s more like analytics and each actor I spawn represents a measurement/ highlight of the location of interest. These actors spawn a form which I fill out with a description which is saved to the actor.

What I need is for this actor to be represented in the list I’ve made, so I can select the actor in the list and view its details and edit them if needed.
