Since a PCB layout is done after the circuit is designed, the drawing
of it doesn't need to include actual connections between the layers.
In fact, holes and plate-throughs are actually specified in separate
files from the trace layout.

Anyway, what you are looking to accomplish could be partially
accomplished by allowing objects on  one layer to connect to objects
on another layer.

A fuller accomplishment would be achieved by putting references to the
original object on each layer you want the object to reside on, rather
than reworking Dia's layers.
