I tend to combine w-2's from the same place, as long as they do not have withholding. The total is more important than the number of W-2G's.
Back in the olden days we only need to report total winnings. Even today, I think that would probably work with only 1 W-2G.
Be sure you charge the client for this time to input and then again to delete. You can add that cost to the gambling losses
