Availability selection AND / OR

Currently when you select multiple availabilities for an event, it shows up as options with an "OR" function. So if I have Availability A and Availability B on an event... It will show both options when both are available (OR) It will show A when B is unavailable and vise versa (OR) But we cannot select an AND option for availability so it *only* shows when all are available (ie. if A or B are sold out, you CANNOT get the event because it requires both to be available to be booked -- A *AND* B must be available to be bookable) Where the rest of the logic is already there, I imagine this could be an added checkbox to the availability section.
