Assembly and parts STL export in NX

Hello Forum,

I have an assembly build in NX v11. Due to external requirements I have to export the assembly in STL.

Is there an option to export each and all  parts associated with the assembly to different STL exports without opening each part separetly and exporting. Is this possible?

I have already the STL export of the whole assembly but I would need all the parts in STL too.

 Thank you
