Grouping and Collapsing Rows with Label?

Hey all,

I know you can create a group of rows or columns manually and collapse them... but I wondered if there was a way to set up these groupings automatically, say based on a date range? So everything in "May 07" gets put into a "May 07" grouping?

And is there a way to label these groupings to make them more easy to identify? Thanks, I know I might be asking a toughy here... =)

it's kind of like that... but there are no labels.

the best example I can give is like the attached image... if this is even possible. Essentially, based on the date field, the row would auto insert itself into this "group" and when the header of the group is clicked, it expands or collapses.

oh definitely! this is great! thank you
