Ref Des Format

I was wondering if there's anyway to change the format of a ref des. The program automatically counts and labels them, but for large projects, my company labels them with [Sch pg num].[Instance]. Currently it appears as theough the EEs are doing this manually when making a schematic. Is there any way I can reformat the automatic Ref Des creation to to this?

Thanks for any help or advice you can give.

I don't think you can change that during the schematic creation, but in allegro there is a skill function axlRenameRefdes(old_name new_name) allows you to...

There also is the external command 'reftxt', it's documentation/help file is shown below:

reftxt: Allows renaming of a design's refdes via a text file.

Command line:
reftxt <rename file.txt> <in design> [<out design>]

If out design is not given overwrites the in design.

Logfile: reftxt.log

Rename file syntax; one refdes rename per line:
<current refdes> <new refdes>
