If you are using the default layout then on the right of the screen next to the “Inspector” you will find the “Node” section. Under the “Node” section is where you will find the Groups and also Signals.
Hello and thank you for your answer!
I can see the Node section and I can add a group but I have to do it individually, one by one. If I try to have more than one selected it tells me to “select a node to edit signals and groups.” Is there a way to do it selecting more than one node?

you can create one brick node and add it to group brick
Inside the brick node you can have sprites for each design.
Hide and show it with script.
You can create your Levels with tilemap and change/replace on runtime the cell with your brick node.
