Have 2 create 2 new date fields after export from MS project 4 piv
 

A database created from MS Project contains two fields that I'm using in my
Excel pivot table; year and month. The problem I'm having is that these are
actually number and text fields and don't work properly in my pivot table
until I conver them to date fields in Excel. I custom format the year as yyyy
and the month as mmm. Once I have done that my pivot table works by grouping
projects by year and by month. I'd like a workaround so that I don't have to
go into Excel and create these two new fields ech time I refresh pivot table
data. Any suggestions?
