Assigning new tracks to old tracks

[tesorrells]

Say I have an object and for one reason or another its track changes from 1 to 2, but on my end I also determine that 1 and 2 are the same. What would be the best way to set 2 back to 1 before it is displayed to the user? SORT will know it grabbed a second track, but due to a check that determines this second track is the same as the first, it will set "new" track data to the first one.
