Yes you can do this. First you have to "Group" your items by "Due Date".
(Ask if you don't know how to do that). Now you will see a light blue bar
with yesterday's date as a header. Just click and drag the header of the
Group from Yesterday's date to the header of Today's Date. If you don't
have a group hearder of today's date, then follow Tom's suggestion, just
change one item of yesterday to today, then you will get a hearder with
Today's date, and can follow the above directions.Now you can change "Group"
to none if you want to, and all of your yesterday items will still be listed
with Today's due date.
