Option for non BR/Gauntled players

So this is a bit annoying for me and I can say I am not the only one, this is bothering a big chunk of people. As a core BF player I would love to play the core game (all the original BF modes like conquest, rush, etc...) and not to be forced to play BR or Gauntled mod for the challaneges. These game modes are not for everyone, so I thought there should be a option for a player who picks if he wants to recieve combined Challanges including BF mods and BR/Gauntled, or just BF mod related challanges. I know there are Rerolls but they not work for the Bonus missions. And recieving 2 weeks in a row the BR quests isnt fun. Not sure if this post makes it to someone who can really do something about it, but I tried. 

Have a lovely day! Peace!
