Shelley,
I believe that's all the AUX pages that you can have with TNEW; we recently did raffle tickets for our gala and we wanted to control the quantity so I just set it up as a new Production in Ticketing Setup and had it display on the AUX page for purchasing.
If you don't care about quantity control, you could put it on one of the Contribution pages; we have one Contribution page handling our Annual Fund and membership donations and the other Contribution page handling donations to patron support of our gala and specific gifts to our Integrated Campaign.
Thank you,
Brian
