I have the latest copy of fogbugz and i am trying to see if there is a plugin or any other way that anyone is aware of to roll up custom fields. For instance, i want to use a custom field for QA estimates but i want them to be based on a subtask. ie. QA Work item is the parent and QA Tasks are the children. These are estimate fields and i want the QA Work item to have an estimate of the rolled up estimates on the QA Tasks. Has anyone tried to do this with any success? They have the capability as a default but we use that for engineering estimates.
