Configure custom max task length on desktop

If I have a very long task (say, 5hr) and I drag it from the sidebar to my calendar, it shows up as a very long time block. I have to place it, then scroll way down to shrink it to fit my available time.

The AI planner has a setting, "Break tasks of X hours into multiple sessions of at least X minutes". I'd like a similar setting for manually dragging tasks to the calendar. Just to make it a little easier to schedule long tasks in small chunks.
