One of the guys at work wrote some custom code to do this, the ouput look something like:
RefDes Part Number Page-Zone Generic
C1 10-000XX-01 9-H6 0.01uF
C2 10-000XX-01 9-H6 0.01uF
C3 10-00XXX-01 9-G7 4.7uF
I can't share the code with you, but what he did was use Perl to access the "ASCII Out" command and out put all of the pages of the design and then parsed the file using Perl. By doing this you can probably format it anyway you like.
If this is something you really need, you might want to put a ticket in with Mentor to see if they can give you a solution.
