At this point I chalk this up to one of two things. Either utter greed or utter ignorance.
If it's utter greed, it's because they don't want more than one person in a household playing this game as their own character. They want everyone to spend the money to buy their own copy, thus they have blocked the ability for more than one person to complete challenges in the game.
If it's utter ignorance, it's because the team that created this probably weren't even with the company back when EA ruled the golf game world, thus they have no clue this was even a feature.
Either way, the deafening silence on the matter tells me we'll never see it. Time to move on to 2K23 which, guess what, allows you to create multiple golfers and use them against each other. Imagine that!
