At Rill Architects we run ArchiCAD on macOS. If you work at Rill, this is your stuff. If you don't, but you work in ArchiCAD, you may find something interesting. Anybody else, I don't know.

Short Name
So that a zone can be shown with an abbreviation in the plan where there's not enough space, and with the full name in schedules where abbreviations look awkward.

Put the abbreviation in the Short Name parameter. If the parameter is empty, the full name is used in plan.

Another idea would be to hard-code standard abbreviations for typical room names.
