Rhino Worksession files won't be exported to Keyshot?

[octav1an]

So I was having this issue for some time now, when I have a worksession in Rhino where several rhino files are attached to the worksession, the geometry from other than the active file won't be exported to Keyshot. Is there something else I can do except select all, copy, paste in the active file and render?
Thank you.

If someone will have the same problem in the future, here are two python scripts I wrote to export and update geometry. They will temporary copy all the visible geometry from the attached files maintaining the layers hierarchy , send it to Keyshot  and remove the copy.
