Add multiple children to a node at once

[mehekk-TG]

Pretty straightforward, but I think a lot of people would appreciate not having to go back and forth just to add a couple of Sprite2Ds and a CollisionShape2D

Maybe there could be a toggle button in the 'Create New Node' menu called "Select Multiple", which will allow you to select multiple nodes, and the nodes you select will also have a number next to them to change the amount that will be added.

(Sorry if this isn't enough details, I don't post feedback often)

I'd prefer having keyboard modifiers that allow you to choose whether to add further nodes after creating one node (i.e. making the Create New Node dialog appear again instantly), and also chose whether to add the node as a child or as a sibling.

See godotengine/godot#79469 which implements this, but I ran into issues while implementing it that I don't know how to resolve.
