Adding objects to linked collections

Hi everybody,

hope this is the right place to post this question.

I’ve got a collection linked to another scene. The collection contains several objects. I wanted to change one of them and make it two objects (seperate selection). Now the second one (with a different name “object.001”) won’t show up in the linked scene.

Also: how to add objects to a linked collection?

Hope you guys can help me.

Regards,
Johannes
