List of Actors (Pawn) in a Widget

Could a structure be related to variable data and indexed to the instance of the pawn?
Because each “ant” must have a different age from that of the others, since they are not all born at the same time.
the list must include the data contained in each ant and display the update of the variables during the games

Yes, I indeed have a saving and loading problem, how to make the list resume each time the previous entries and add new ones and save them.
