Not sure exactly what you're asking (i.e. get a "different" three day), but if you mean where you can use the WPF&M options - it's up to you as long as (like Deb explained) you use them all within the life of the MYW pass, unless you've added the no-expiration option.
So, you could go to Blizzard Beach three times; or Typhoon Lagoon once, BB once, and DisneyQuest once; or DQ twice and Pleasure Island once; or any combination. You DO use a separate WPF&M option each time you enter one of those parks - i.e. there's no 'hopper' option; so if you visit Blizzard Beach in the morning, DisneyQuest in the afternoon, and Pleasure Island at night all on the same day, that's it. You've used all your options.
