Can we work to get this in COD7?

+1 would be amazing to have. This helps drive interest (hey cool, 2k people are coming to this camp!) and ALSO helps serve as a nudge for stragglers; 'heyo, there's literally 2 tickets left and you will be devastatingly sad to miss out on this event if you don't buy RIGHT NOW'.

This may require some math, as I imagine some camps may use different ticket types ($0, full price, whatever) but I think the need (or super want) for this kind of marketing feature is universally shared.

If someone wants to slap a napkin wireframe together or provide a good description, this seems fairly straight forward to produce.
