Geometry nodes: Instancing from local origin versus global origin

I’m distributing tree meshes from one Scene, “Tree_Workshop”, to another, “House_Main”, in my *.blend file. When rotating the instanced items, they rotate around their global origins versus their local origins. For visual convenience in the first Scene the trees are spaced out for construction. When distributed via GeoNodes I’d prefer the trees rotate around their local origins.

How would one do that in Geometry Nodes (2.93.5)?
