MLS edit

To all editor experts, I would like to know, and advised on how it can be done, but although FM is out every season, but until then, is there a way to make the MLS like it is in real life, with Orlando City Soccer Club and New York City FC to join in 2015, David Beckham's Miami team in 2017 etc etc, how can this be incorporated in to the game so we/I can play in 'realistic' world.

Thanks in advance for any reply.
