Frustrated with not being able to figure out which of 3 nearly identically named commands properly overrides a linked armature so that I could re-use a linked rigged door asset multiple times in one scene, I tried making something similar with Geometry Nodes.
The trick to being able to link to a node network that utilizes several real objects without those objects also being linked to your scene and cluttering your Outliner, is to only link the node network itself.
