Adwords account management : Update all max CPC ?

Hello,

During some periods (Week end, holidays), I want to decrease the max CPC of all my campaigns and then encrease it again.

I have seen you stop/freeze your compaign during some days.
But I don't want to stop it but decrease the bids.

Is there a tool to update (all) max CPC in one click (or based on a calendar) ?

Thanks in advance for your help.

 

You need to use Adwords Editor > Advanced Keyword Changes > Change Bids By %
