I recall that as a Master as well, but keep in mind, all your fellow Masters will be playing on the same greens.
Even as TM, you can't set up a practice round with Tourney greens.
And thereisno option for Legends to setup Championship greens either, we just have to pay our credits, enter the tourney and see what happens.
I suspect it's the same fro Pros/TP's too, not sure.
What you can do is go to the tourney's main page (not from the game client window), select "Open Tournaments" and see course conditions before hand.
Another thing to so, is set up a "scored" MP game, no credits won or lost this way, and select TM+ for player ranking.
