Batch actions for Tasks (multi action)
It would be very useful to be able to either have a) the ability to copy a group of subtasks to another task, or to b) be able to create a task which is not marked as completed until each person it is assigned to clicks that their part is "Complete". The scenario this would be useful in is in kind of like a class-room setup for a team or class. Personally, I have multiple papers that I have sent home with team members and that they have been asked to complete. Instead of creating a main task called "paper 1" and then a subtask with each persons name (which gets very tiring, especially when there are multiple tasks like this due at different times), either of the above solutions would be very useful! Another way to visualize idea B, just to clarify what I am saying, is when multiple people are playing a game together on the xBox - the game doesn't start until each player has marked themselves as "ready".
This feature idea is kind of like this (http://bit.ly/1TTFtFT) one, but not quite the same.
One last idea for how to do this would be the ability to create a task and assign one copy of it to each selected individual - but do so in a way that the task doesn't show up multiple times on the task list (just once overall).
Sorry for the long post, and thanks in advance for considering the ideas!
