I'm not an Eagle pundit either, and I've never found how to do this:-(. So,
I've adopted a more "brutal" way : I "print" each eagle mask with PDF
Creator, and then I merge the different images with a pdf editor (this is a
good way to optimize the placement when you are using an expensive support
like PnP Blue or other transfer films)
