Change monthly challenge

Hey,

is there a way to get a different monthly challenge? I'm really annoyed because it says that I should get so many active calories this month. I absolutely hate the calories challenges especially when they are so ridiculously hard... I wish there would be a way to say that I don't want calorie challenges and get another one instead... I want the badge, but I don't want to cheat or try to burn so many calories one month and mess up all my stats just because of that challenge ;(
