When customising a view of a task list and using the filter I can choose
tasks with a due date in the last 7 days.

Is there anyway I can make this the last 14 days? The SQL the 7 day option
gives me is:

%last7days("http://schemas.microsoft.com/mapi/id/{00062003-0000-0000-C000-000000000046}/81050040")%

and doesn't mean heads nor tails to me....

Thank you.
