Mmm, OK just realizing this is PADS Pro you are using and that is more Expedition like, so you are dealing with cells and not decals.
In PADS this is not a problem, however in Pro not so sure, because of DRC is it not letting you save? Or other issues?
Maybe someone familiar with Pro version will jump in on this. I seem to remember back a while in full Expedition this was not a problem,
we used to do this with cells with no problems. But that goes back a number of versions ago, haven't actually used Expedition in a few years now.
