How do I scale all objects in the editor that have a hierarchy?

Imagine Ive created a character and linked it all up with the scene graph hierarchy at edit time (using 'add selection to this instance' in the editor)

..but then I want to scale the complete character inside the editor. How do I do this?

Currently it seems to scale every object individually around its own origin.

Here is a video example: dropbox.com/s/zwyqr5jl9crhrv4/2022-03-30_17-17-50.mp4
