At current I am using Monday.com for project management, having main deliverables as tasks and actions to complete as sub-tasks. I’m tracking the estimated hours of each sub-task (currently using the number field) and using a Mirror column on the main task to get a summary of the hours of all the sub-tasks under it. This is working splendidly. However, now I’d like to get a summary of the total estimated hours of the main tasks of the group, like how a number field would usually do this with a summary at the bottom of the column. I’m struggling to figure out a solution for this issue, any help would be appreciated.
