Importing external glimmer components as children // glimmer addons

[hoIIer]

I'm looking to build an embeddable glimmer component that would make use of a few existing glimmer components from an ember app (form component, changeset etc, could be moved into an addon).

Is it possible to import and render child glimmer components within a parent glimmer component, either explicitly or through a glimmer addon?

If not, will this be supported in the future?

Thanks!
