Tickets for members only

Hi there -

I've installed JTicketing for a client website. My client sells tickets to community events. Members of their organisation are eligible for Members discount, while general public pay full price.

Is it possible to create a ticket option for members only - for example, only visible when users are logged in? Or alternatively, is it possible to require that members enter their username (as proof that they are members) in order to purchase 'Members Only' pricing?

Thanks
