Add and remove child widgets depending on contents of an array in Scroll Box UI (or better method)

I’m trying to make a Pandemic game but I’m stuck on how to properly display cards on the screen.

Target:

When a player draws a card or discards a card, the UI should be updated immediately. The text blocks are the city names that correspond to the city card and the symbol represents the disease color of the card.

For now, I don’t need to display the player names (adding them later)

Details:

Each card in the UI is a widget called ‘Standard_City_Card’ containing images and text blocks

Each of the player cards are actors (the name of the actor is ‘Standard Card’) containing information such as the city name (String), the city ID (int), and the disease color (int).

The cards that the players hold are stored in a different array called ‘Player Hands’ and the variable type is ‘Standard Card’ for direct referencing.

Is there a way to add the child widgets or move them in-game using blueprints? If not, is there a better way to do this?

I was thinking of deleting all the child widgets then adding them again with the new cards but I wasn’t able to figure out how to delete them that and adding them to the UI
