I see the point, but hiding the clutter is not a solution. The mess is still there and it’s better to deal with it on time, rather than fake that everything looks nice and clean. If someone has a recurring task to do on a specific day, it should be very clear both for him and the project or portfolio manager because it affects the short and the mid-term planning.
The bottom line is that Workload is a paid feature that is not well engineered and it has many leaks (see also this issue). Right now it’s just something that looks nice on tutorials, but as we see here, it fails to support managers on planning activities since it needs a lot of time consuming workarounds.
