I want to write my own popup control with predefined buttons and some behavior.
I created a separate scene and build a layout using ‘Control’ section of nodes (margin, h/vBox containers etc.)
And now I need to specify the position in this tree where all the nodes, specified in consumer tree will be placed.
e.g. I have Main screen:


These label and button should be located under VBoxContainer in MyCustomPopup tree:

----Other containers

How can I implement it?
