Describe the solution you'd like
Example: If you have the task "Car must be washed once a month. Choise month"
and you have a dropddown list with every month "Jan, Feb, Mar,...Dez"
the selected month should be eliminated from the list so other users can't choise it (enought if washed once a month).

Long missing feature in google forms: Can only be done via add-in.
