For quick and easy I believe you are SOL.
I'm sure a macro can be written to prepend the first 9 in your revision table to add a 0.
But since revisions usually come one at a time, that probably won't be the best answer.
This looks like an enhancement request in waiting. Please contact you VAR at your earliest convenience.
Solidworks PDM has the ability to create a list of any revision characters that you could possibly want, if that's something you might be interested in.
Hi Rick / Austin,
I thought that was the case but thought I'd better check.
No don't use the PDM and have no plans to do so, so it looks like a talk with the VAR.
