Preset dates such as last 7 days are counter-initutive and should be changed

When you select 'last 7 days' it include the day you are on.  However, this is counter initutive.  For example, if today is Monday, June 7, 2010, and you select:

Select 'last month' --> you get May data [not including this month]

Select 'last 7 days' --> you get data for Sun-Mon; most people expect and based on logic above, you expect Mon - Sun [i.e. not including today]

It would help to change this to avoid confusion.  Our company is new to Omniture and we have several hundred users.
