Favorites could be subcategorized so that you have your favorite rides setup as fighter or attacker under sub tabs. Then under those tabs his P51D under fighter would be 6 guns, 75% fuel, while under attacker 6 guns, 75% fuel, 2-1000, 6-rockets. Then he is on the hook for his personal setups under each tab. Selecting from either tab would auto set the scoring state.
Or create two load out presets for aircraft that can be scored fighter or attacker. To which you setup your load out then direct that to a fighter or attacker bin with some way to edit it to make changes. Then when you click on that bin and hit launch your plane is auto set for it's scoring type.
Does score even matter anymore?
