Default [Q] Is there a way to sync ALL folders with Exchange by deafult?

The new Kit Kat mail app looks great, but I need to find a way to make it sync all folders by default, or to be able to select them all easily instead of going through each one's settings. The problem is that my users sometimes have more than 50 subfolders, and I can't possibly do this manually for everybody...

Thanks for any hints on how to accomplish this.
