During multi-level event registration, allow users to apply the same option to all in one click (both the invitee and their guests)
While observing our event registration process I noticed users are forced to click into each event and sub-event listed on the registration form to select an option. In most situations, the options have been copied from the main event and applied to the sub-events. So they are exactly the same. For the registrant, often the option does not vary from event to event. The users said the wish they had a button that said "Apply to all" so once the main event is registered for, they can apply that same registration option to the sub-events, too. We have several large multi-level events that it becomes quite tedious to click on the drop down box and select this same value over and over. This is especially true when you have copied the registration options from the main event so each within the sub-events are exactly the same. It would be ideal if this 'apply to all' feature would be available for both the invitee and guests.
