Please allow multiple choice question to limit how many people can select each choice. e.g. I have have a class with 3 timing:

sorry, I might have a class with 3 timing: 9am - 11am can only be picked by 12 people 1pm - 3pm can only be picked by 8 people 4pm - 6pm can only be picked by 12 people. There should be a hidden counter somewhere to count how many people had selected each choice and then hide the option when there are total 12 people who had picked 9am - 11am. Others who visit the form later should not be able to view the 9am - 11am timing anymore since the class has reached maximum capacity.
