Inheritance group defaults to all descendants

hi all

I faced one issue which is confused me (I don’t know how to do it)
I’ve set defaults for top level group (default wrehouse, cost center for organizations), but is isn’t inherited to its descendants (item groups and items)

does anyone know what I’m doing wrong and how to do it right?

a little refinement about the question:
it doesn’t work, when item is situated inside items group, which is under another items group

but the main question is that it doesn’t work at all in REST api post requests.
for example, when I’m creating sales invoice, I need to pass all data about items, which can be binded automatically via item defaults (cost center)
