Adding up story points for queries?

Have you tried creating a plan for the Iteration / Timeline these stories belong to (assuming you are looking at the stories of the same iteration) ?

I would also like to do the same thing. We often use Tags or the Feature field to denote a particular requirement and I would like to chart this out to show - Requirement X - Total Story Points. Are there are any plans for adding this functionality?
