Once you have used your 1st 3 Selections (or Redeemed 1, let 2 run out/Redeemed 2, let 1 run out) then just go to the Fastpass Kiosks at the park and you'll see a button to add your additional FP.
And for the selecting seperated members for different fastpasses, it's possible. I don't know if you can do this on MDE (be suprised if you couldn't) but AFTER you have made your 3 selections, just modify the experience by selecting the party members in you group who want to modify the experience.
I think it is partly to discourage use of these extra passes. The first three are super convenient, while any others are less so because not only do you have to use a kiosk, it must be a kiosk within the park you are selecting FP+ from. Some people won't do it just because of that, and others won't do it because it isn't super obvious that you can. Who knows the real reason, though. The software update thing makes complete sense, too. They can easily upgrade their own stuff, but pushing it out to everyone else takes time, and since this is something that will likely put more strain on the already strained mobile platform, they may be working some kinks out first.
You can say that again! We were not even allowed to walk up to the kiosk unless a CM was assisting us. We were only allowed to scan our band. We were not allowed to even touch the screen, CMs did it for us. So annoying.
If this happens while I am there next week, I will make a point to let them know I would rather do it myself. I may even drop a hint to Guest Relations about it, because if they really won't just back off then I know my group will be uncomfortable. I love when CMs go the extra mile, but they need to take the Apple approach - learn to recognize when people need help, and when seasoned MyMagic+ users (or those who just want to figure it out) just want to do it on their own.
