Hi Is there a way to make a layout cell (of comp and trace) that can be placed in many location within PCB layout?  More importantly, in a manner in which autorouter do not fiddle with the traces at the subcircuit level. I'm doing a layout, without schematic, that includes multiple (6-24x) copies of a simple subcircuit.   For multiple reasons, its is highly preferrential to creating a fully-routed layout-subcircuit and placing it an array rather than individually placing each comp of each copy of the subcircuit and then routing. Thanks
