If you are holding leveled classes together, you will use the 06 of the class for Level 3 and the correct leveled class with the Held With class set to the 06 class so they are concurrent.
For example: if you are leveling Yearling Mares (originally 1054), you would add 105406 and 105403 to your show and change the Held With field of 105403 to 105406.
