Two Google Accounts

I would rather focus on writing, but I’m faced with an analytics issue, so here goes… I just started working with a client who has two Google accounts - one for their analytics and another for the Adwords. So, they log into one account for their website analytics, and another account for their Adwords.

Is there any way to consolidate the two without losing all the history they have in their analytics account? I’ve done the thing where you give each account access to the other account. But my sneaking suspicion is that they would have to start analytics all over again with the code from the Adwords Google account in order to have it all in one account. Am I making sense?

Thanks,
Andrea
