Create Tasklist items w/o setting dates

I'm running GW 2014 SP2 (not R2) and do not see a way to create Tasks without start and end dates. Is there a way to just create a basic Task that you can checkoff without giving it a start/end date in R2 or SP2 (in case I missed it)? I see where you can create Quick tasks from items in R2, but can you also create a Quick task (not from an item) in the Task folder and NOT assign a start/end date to it? Our users would really just like to create basic checkoff tasks in the Tasklist folder without dates.
