Please help Pleeeeeaase

I imported my model from Revit with Datasmith. How do I set it up to listen for a change? Also, it looks like if i add any blueprints to the datasmith actors, it removes the datasmith information that was attached. I need that info to stay intact.

maybe i have to revisit the basics. I cant even assign a blueprint to multiple actors.
I’ve never used game instance, so i’ll be toying around with that too.

thanks for the input so far!
