Datasmith DirectLink in editor and at runtime: how to merge?

Hi all,

I’m currently using Datasmith DirectLink to synchronise an ArchiCAD model with my game in the editor, and this part works.

I would then like to use Datasmith Runtime to have the DirectLink to “persist” also at runtime.
What I’m hoping to get is that I synchronise all the changes between ArchiCAD and the editor, package the game, run it, make further changes in ArchiCAD and have those changes synchronised with the game at runtime.

Datasmith Runtime is working but it is re-importing the entire ArchiCAD model instead of merging only the changes that I made, and I found myself with double the meshes and double the textures

Is it possible to achieve what I need?
I can’t find any info regarding this in the documentation and examples available.

Thanks
