Hi corsi_lorenzo,

Yes it is possible.
Make a Publish geometry in your parent model by using Insert>shared data>publishgeometry and select the surfaces which you want. You will find an icon of publish geometry over there.

Then open a new file and select Insert>shared data>copygeometry.
Then open the parent part and selct the default position. Now scroll down the menu and finally select publish geometry surfaces.
I hope thiswill solve your problem.

Thanks,
