Dragging Plan to an end date?

I have multi-week training plans, and I have race’s in my calendar.

Am I missing how to drag a plan onto a race day (the ‘end date’), and have it populate backwards in time, rather than having to manually work out which date I need to drop the plan to so that it ends up finishing on the correct date?

I completely agree and was about to add a request saying the same thing.

Generally when you’re adding a training plan you are working backwards from the event not forward from a date. Every time I try to set up for an event I find myself going through the same cycle of - calculate backwards, add it, getting it wrong, delete it, do again…

It is difficult to imagine how the drag could do both start or end, but it could be done by something like a ‘add to calendar’ button where you specify the date to add, or maybe a preference whether dragging indicates start or end?
