Bring Imported Datasmith data to Game Map

Hello all.
I am just new with Unreal Studio and I imported some 3ds models via Datasmith.

After that, I delete them from World Outliner. They still appear in Content Browser.

Now I want to add those object to Game Map. But I can drag DataSmith Scene Import Data do Game Map.

How can I reuse my imported data?

Thank you very much.

In the moment, you’re stuck. You need to reimport. We’re solving and improving this in the next update
