I mentioned it in another time tracking based thread, so I’m not going to go too extensively into it here (just link over there - Improvements on Time tracking column - #184 by EMorton), but the overall gist is that another solution for this is instead of the time tracking widget, use the workload widget and some creative column use to indicate how many hours someone has worked each day/week/month. Can allow for setting a ‘capacity’ to indicate when someone’s hitting their total hours for the week, as well as be filtered as well by any number of fields/columns that you add to the items or subitems.
For example, here’s a snapshot of what it looks like with a selection of hours against a few filtered tasks from the last couple of weeks.
