Sharing items from one dimension file to another

I am working on a file with another designer. We started with the same 3D assets but each of us has done some different things with texturing and layout. Is there a way i could give her one of my files with textures to put in her layouts without giving her my Dimension file and have her try and replicate everything in her layout (camera moves, background changes, repositioning multiple models). I feel like the ability to copy and paste models or at least put them in CC would be amazing for this. Having the ability to import a piece from another dimension file seems like a pretty generic normal request. Is there a solution?
