WIlliam,
In Expedition I have created a two pin schematic symbol and a footprint
with overlapping pads that can be populated on the backside underneath an
A2D. Mentor flags the shorted pads but only if you check drc within the
footprints, other wise the design is drc free. I haven't tried this in
Allegro but the principle should work the same.

Hello all and thanks for this ton of mails to read :-).
In fact, I saw that a lot of people proceed like us.
We already use 2 of proposed workaround, the connect line on a non etch
signal, but risky,
or the component (SMD or not) to join them physically,safer.
Of course the main goal is to have 2 differents nets in Allegro, to treat
them separately, for placement, routing, separate plane and so on.
But I learned a lot of things with this thread...
Thanks, and have all a good week-end.
William.
