Move asset/assets from one USD scene to other?

In cinema 4d I can copy paste objects from project file to other.
How can I do this with Machinima?

I bumped in to corrupted usd scene with this problem yesterday:

So I would love to build this again, by bringing in the houses & other props to a new fresh USD scene… So I could save the work I did.

Hey, I found a solution for this. I just simply dragged in to new fresh USD scene an other USD file with many objects. It works!

Right! USDs can be referenced into other USDs, so you can save a group of them together as a new USD and then place (reference) that new USD into a different USD stage.
