Tasks to show for both in calendar & in sidebar, by *same dates*(either planned or due dates)

I was having trouble using Morgen not understanding planned dates vs due dates and trying to use Morgen in a way I've found before to have worked so well for me before with another task/calendar app.

Which there is 2 ways to go that would work equally well, but I would love either way.

One way would be able to sort tasks in sidebar according to planned dates, possibly with an option to sort by planned end dates OR sort by planned dates (maybe have both options?) - and of course, with this way, planned dates would be automatically updated in sidebar when changed in calendar, and vice versa - any planned dates changed in sidebar will update planned dates in calendar.

The second way that would work equally well for me, would be to show the tasks in calendar according to due dates. - and, the due dates changed in sidebar for tasks would be updated in calendar and vice versa-and anything changed in calendar would be updated in sidebar.

Simply, I would greatly appreciate to view/sort the tasks according to the same date, whether by planned dates, or due dates in both formats, tasks sidebar & calendar
