How to access linked objects from a linked collection? (Blender 2.8) How can I access the linked objects inside a linked collection on Blender 2.8?
Inside the view layer navigator I cannot see the objects inside the drop down.
Linked Collection
  |
  |-&gt; Linked Collection
        |
        |-&gt; &quot;Nothing&quot;

I can link the objects individually but I need to preserve the Collection hierarchy, because:

The scene is quite complex, and I cannot know (easily) which objects are inside the collection I need to link, inside the list of all objects.
If the source collection has new objects added, I need them to be added (which is the behavior of the linked collection).

Any Idea how to do it? Thank you very much.

My problem with more detail:
I'd like to be able to access the linked objects inside a linked collection so I can change the materials for the linked objects as they define here.
I can make it work with Blender 2.8 linking objects directly and using a Library Override for the object, so I can change the material data block. But, I cannot find a way to access the linked collection's objects... to do the same, preserving the versatility of a linked collection.

Edit:
I found in the documentation Making an Instanced Collection Real which supposedly archives what I need, but does not work (at least I cannot make it work) with linked collections:

&quot;Simply select your Instance Collection and press Shift-Ctrl-A to convert the collection into regular objects&quot;.
&quot;Note that if the instanced collection was linked from an external file, the Object Data (mesh, materials, textures, transforms) will also still be linked from the original collection&quot;.


Edit 2:
I need to use the same source file collection, and be able to have instances with different material overrides locally. So I can have the same objects with different colors in different instances.
I use this:

I set it to appear in my favorites panel. It opens the linked file; and when you are done; you
