Admania – Adsense WordPress Theme

I’m using the Admania theme, which has built-in spots for AdSense ads. But right now, I have to add the ad code manually to each page, one by one.

Is there a way to replace those manually-added ad slots so I only need to insert the AdsMania code once, and it automatically shows different ads on each blog post?
