time blocking - splitting longer tasks over multiple days

Is there a way to split longer tasks and time-block them across multiple days? For example, I have a task that I estimate will take 10 hours, and being able to break it into 2-hour blocks distributed over 5 days would be ideal. 

I use the time tracker occasionally, which helps, but when the task is unfinished I have to drag it into a new day, disrupting any schedules I've already set up. I've tried manually creating multiple blocks in advance to prevent this, but it becomes overwhelming to have several entries with the same name.

If there is already a feature like this that I'm missing, or if you have any suggested workarounds, it'd be much appreciated!
