Group By reporting for DOC Export

Has anybody had a need for being able to generate Word Document reports that are grouped by a specific column ?
We may have a need for this and before I go and code it up I wanted to see if there was any interest or if this work has already been done.

I'm envisioning that the same way in a Page display using the Table style, for the Word Document Style under Feed one would be able to select a column to group the data by.
