Custom fields totals fro parent-child issues
When we have a parent-child issue relation, some of the standard fields are calculated based on child issues. For fields like estimated time and spend time we have totals (sum) calculated and presented on the issue page. There is also issue query column available to show the data.
I'm requesting same feature for custom fields that are numerical fields. There should be a checkbox in custom field configuration if this feature is enabled or not for the field.
