No.
But it would be neat if it would. Maybe the code for the slotting 
mechanism could be reused to achieve the trick.

And let the script edit the list of new components emitted by gsch2pcb.

I don't like the slash, because it makes the component names extra long. 
So I put these lines in a local gnetlistrc:
 (hierarchy-uref-separator "")
 (hierarchy-netname-separator "")

In addition, I set the refdes of the subsheet symbol to a single digit. 
That way, the refdeses stand a chance to be readable in in silk with 
a three layered hierarchy.
