I don't think this would be possible, as PD would probably have to obtain licences to use Microsoft Excel. Trust me, their very picky about that (Microsoft). Considering that Sony is a direct competition, I don't every expect it. The other issue with this is that not all players who'd want to use the spreadsheet option use Excel... but I don't know enough about the options. Maybe someone can think of an idea to that end.
A spreadsheet doesn't have to be Microsoft Excel. Or did the OP imply it's got to be Microsoft Excel?
Edit: I'm all for csv.
Call it "open office"
