ORD annotating horizontal cardinal points - abbrev

I would like to use other than default English abbreviations for horizontal cardinal points to annotate alignments: PC, POB, POE, PT, etc.

Depending on project location or client we need different abbreviations to be applied, eg: English, Polish, Swedish or different for Highway Agency and Local Roads Authority and completely different for airfield projects.

Can anyone advise me? In general I find these new way of annotating quite friendly but a little assistance is welcome.

Thanks.

Adam
