I see that you can change the time interval displayed within the calendar from 15 minute intervals to 10, 20, etc. Is there a way to change the intervals displayed when you click the "Time Input" button when making an appointment.

eg. I can set the time interval within the daily view calendar to 20minutes. Select a time of 1:40pm to start an appointment, click the time input button and it immediately shows a start time of 1:45pm
