Making component references globally unique across multiple schematics

$

Hello,

I am adding to an existing project in Allegro Design Entry with multiple schematics, and I want to ensure that component references (locations) are globally unique, i.e. that no two components in any of the schematics have the same name.  Checking each schematic for internal duplications will not do.  If I can generate a BOM for each schematic, I can merge them in a spreadsheet file and check for duplicates there.  However, because the schematics are in a rough draft state, there are errors, so I can't package them in order to generate the BOMs.

The errors are mostly caused by unnamed components named R?, C?, etc.  The packager detect the presence of two components with the same name but different values, and refuses to proceed.

Is there a way to generate a list of the refdeses in a schematic without packaging it?  Alternatively, can I force the packager to complete in spite of the errors?

Thank you,

Chris
