Ring ceremony association

How to change team which will get rings and trophy before first game. By default it's Miami, but let's say I want to make Spurs to have that type of ceremony?

If there's a way to set the Spurs as being recognised as the 2013 NBA Champions in the game's history, that might work. I don't know if it's possible to edit that, but if it is, it'd probably be the place to start.

Only way to do that is to edit certain values in roster (Awards tab), which I did, but no luck, still Heat.

That's a shame, worth a shot though. Perhaps it's hard coded for that first season in Association.
