True, there are some definite limitations. For the duration I enter the first one, hit return to take me to the next line, enter that one, return, etc. I can blast down through the list of tasks pretty quickly as long as the days are the same for each task. Same for hours. Assignee is a little slower, mine so far have all had just one assignee so I can copy their name, paste it into the first line, wait for the type-ahead function to bring up that person, hit return twice (once to select that person, and again to bounce to the next line). So that one is a bit slower waiting for the type-ahead to know who I want, but not a deal breaker for me and still faster then entering each task separately. Entering the assignee into the parent task populates all the tasks, but then that person has the parent task on their Home list for the entire duration of the series - not ideal.
