Possible to automatically flag items due today?
 

I have a perspective called "Today" which shows only flagged items, grouped by context.
This allows me to review current projects and choose what I want to make sure I have finished today by simply flagging it.
I was going to knock up a script that automatically flagged any items with a due date of today, so that they appeared in this perspective too, but before I get my hands dirty, I thought I should check that wasn't already a way of doing this.

Anyone?
