Collections with the Asset Browser (Linked only ?)

Hello Guys !!

I finally learning how to use the Asset Browser (Blender 3.2) and I have a question I can’t clear.

I have some spotlight I made with a system to direct the light where I need. So it’s multiple parented objects in a collection to make things easier. But with the assets browser, every time I import the collection, blender create an instanced collection (no matter if I import with “append” or “append (reused data)” and not “link”)
And I tried “make instances real” but after that all the objects are unparented so it’s not an option…

Someone has an idea if it’s possible to append a collection with all the assets separated ?

Thanks in advance for every clue !!
