According to the Inside AdSense blog better management tools for AdSense users are on the way. The new tools will allow you to manage your ad units from within your AdSense account, meaning that settings such as colors and channels will be saved in your AdSense account every time you generate ad code. What this means, practically, is that you will no longer have to manually replace ad code on all your pages every time you want to make any changes. Want to change all the borders of one size ad from red to blue? No problem, with just a couple of mouse clicks it will be done.

"We'll be rolling it out in phases in the next few weeks. When you see the "Manage Ads" page appear under your AdSense Setup tab, you'll know the feature is available for you to use" Google says.
