Start sprint date and end sprint date in Agile for TFS2010

I'm trying Agile with Team Foundation Server 2010 for the fist time.

I'd like input for each sprint a start date and an end dat开发者_JAVA百科e but I think that is not possible actually.

Do you have some hints how extend it for this data?

Enri, each sprint will have an excel workbook associated to it. Within that, in the settings worksheet, you should be able to specify the start and end dates.
