Was asked to create a feature request from a support person so I'm copy pasting that to here:

I have been trying to create formulas that could do this and I don't know if it's possible. This would be such a tremendous help in our Sprint Planning...

I can easily use the built in Sprint Points column as a rollup of the total number of sprint points in a milestone, but I cant just easily see the remaining number of sprint points.

I would like a column that can just calculate that for me. I know the above picture is a jumbled mess but I'm trying to show the hierarchy of our backlog and how it would work if my request was setup.

Is this at all possible? Is it do-able through a formula? I have never figured out a way to make a formula take into consideration the 'status' of a task.
