I wonder how I can make a list of abbreviations that may appear, as it were, "subabbreviations". Eg.:

Arist. = Aristoteles, philosophus (principal abbreviation)
     HA. = History animalium (secondaryabbreviation, with small indentation)
     Po. = Poetica (secondaryabbreviation, with small indentation)
      Rh = Rhetorica (secondaryabbreviation, with small indentation)
arm.= armenian
...
The "subabbreviations" would have to maintain the alphabetical order, but in the main abbreviation only.
There is something about this on the mailing list?
Thank you.
