Using preset date rescheduling buttons overrides time property

This is a consistent pain point for me when rescheduling tasks. Personally, I use the time property for almost all of my tasks. So when rescheduling tasks, I have to use the calendar picker and choose the date, because otherwise the time property is lost, sometimes without me noticing. This is especially annoying on mobile, which requires *5 presses* to do! (open task -> date property -> custom -> choose day -> confirm).
