How I can change the logo of the teams created in NBA 2k14?

I want to create a computer game (nba 2k14) but I want to stick my original logo not a logo that the game gives me a choice.
Any program that can do that?
Thank you very much.

This is the logo that I want to put in the game.

I think JaoSming created a tutorial for editing logos in nba 2k14. Just look it up in the tutorials section
