Once all bonus championship belts are unlocked, give any vacant title to a
title holder in the WWE Universe. Then, create any type of singles match, 
and select the double title holder. When you select him, both titles should
be on the line (for example, give Dolph Ziggler the Intercontinental and ECW
belts). This allows every custom match to be a championship match; every 
superstar can have a title match, even WWE Legends. 
Note: This trick works with all WWE Universe belts except the Divas and Womens
belts.
