Hi There!

I have a customer who wants to be able to add custom formats to her Numbers in Excel 2007. 

Examples would be : 

#,##0_);(#,##0)

#,##0_);(#,##0); “-“_)

#,##0_);[Red](#,##0)

#,##0.00_);(#,##0.00)

#,##0.00_);[Red](#,##0.00)

I can't see a way to add these to her Excel so they are persistent across every sheet she opens. I know you can save it per work book, and to the normal template, but that won't help her if she opens a sheet sent to her by a client. 



Any bright spark able to suggest a reasonable solution?
