How do spawn nested objects

I managed to spawn scene1 and scene2 randomly but i have no idea how to spawn objects inside them.

This looks like the perfect situation to make use of containers. Take a look at this example:

drive.google.com/file/d/1qtqeuNNF2tIfZhLrBABtfWaohX1VBLSh/view

In the example, there is a plate and 3 different food items that are all separate sprites. They have been added to a container (https://www.construct.net/en/make-games/manuals/construct-3/project-primitives/objects/containers). When you spawn/destroy a single object in a container, all other objects are spawned/destroyed.

Thank you for this!
