We have added a few custom columns in our project task list that have numerical values. I know that you can create another column and add calculations, but we want it to work more like an Excel spreadsheet with sums on every parent task based on their child tasks (3 child tasks with 2 hours each = parent task sums to 6 hours). This works with the out-of-the-box data points (Planned Hours, Duration, etc) but I can't seem to figure out if we can get this same result with our custom data. Thanks!
