Not sure I know where you are. In the g-code models list there is only queue print in dropdown, print is a extra icon.
The big question is if entering a number, hit queue is faster or easier then hitting queue and change the count.
I guess when we change it sometime like in Repetier-Server Monitor we could add the count in that window. Will actually check if we already can send the copy counter when creating it, so making it possible at least for future versions.
