Purchasing a Water Park ticket

[Whovian86]

I tried searching for this answer, but couldn't find one. I currently have a reservation that consists of hotel + 5 park day tickets package, no park hopper. We've decided to stay an additional day and squeeze in a trip to a water park. I don't want to add the Ticket with Park Hooper Plus option, because I know we won't park hop, but I am not seeing an option on MDE to just add a water park ticket. Can someone please guide me on where I need to go to add this to my reservations?

Awesome, thanks so much! I can't believe I didn't see the link to the Water Park tickets.
