Change google account to different AdWords account
I've been using my free Gmail account for AdWords (a) forever.
Now, I have another account (b) - a google business (apps) account, that has it;s own email, Business Locations (verified addresses), google Plus page etc.
I want to be able to add "Location Extension" at my AdWords campaigns if account (a) and be able to add verified locations from account (b). Please, advice! Currently, at my AdWords campaign's settings I can only add "Locaiton Extension" fro my first (a) gmail account - I can't find how I can add locations form different google account.
