Not on *a* layer in general. Generally on multiple layers. That=92s why =
an object can=92t be associated with a specific layer without causing =
confusion. A container of objects is not a layer and deserves a =
distinctive name.

predefined via/pin/pad. It would also be nice if objects could be marked =
as belonging to a sub layout so they could be selected and moved/copied.
