rerun CM Setup wizard?

is there a command or something on cm 12.1 that allows us to rerun once again setup wizard on reboot just once?

Android Studio 1.4 and new activity wizard.

I have just updated Android Studio to version 1.4, but when I start a new Project and add an activity, I can't find the option to add an activity that uses Google Play Service, specially the one that add the code to connect to Google Drive. Is there any option to do it or that function has dissapeared? Thanks
