Google Adwords Integration: Different google accounts for different workspaces?

I would create different landing page templates for each workspace and have the tracking code in the template. This way you don't have to think about adding it. Otherwise, you can create a program token and add it to the templates and update it for each program/workspace that the page lives in. You would only have to do it once per program, but it is something you would have to maintain long-term.

This is what we do now - we embed GTM into the templates and that way we can tag each page individually.  However, I was refering to the feature that was just rolled out in the March release which syncs all of the conversion information back into the AdWords control panel.
