Break large tasks into smaller chunks

If there is a 6-hour task and only 5 hours remaining in the day, the scheduler won't consider adding the item. But, if we could set a minimum amount of time we want to focus on our tasks (in our case, an hour), it would recognize that the task COULD still be worked on, even if it's not 100% completed by the end.

The alternative would be creating many more small tasks, but that becomes problematic with the process tab once there are 90 tasks or more. Our use case is developing large, custom websites so building each page tends to be an and presently, the estimates for completion we're getting are pushed further and further back because the larger tasks can't be broken up into smaller pieces.
