I'd use a hierarchical sub-circuit, with two pins, and a net between
them. A "short". This could be used to join "AGND" to "DGND". A
hierarchical net-list will retain this, however a flattened net-list
could be produced which still works with existing tools.

Layout tools which "understand" hierarchical net-lists could be of
benefit here, allowing you to view "AGND" and "DGND" connected pads
separately, whilst still expecting them to all to be grouped together as
one big net (e.g. GND).
