Ok, I finally got to create/update some adsense ads, and low and behold, what do I discover? AdSense Units and their management straight from the web interface. Smart indeed, but I have a problem now: if I want to re-use a single AdSense unit, but I want to track it with different Channels on different pages, how can I do that?

It used to be simple (I believe), I could re-use the same AdSense code and just put the different channel id on the actual JS on my page.

But now, the link is done behind the curtains. Basically I have a AdSense Unit number, and I see that number in the new code to put in my site.

But I don't see the Cannel number there; the channel Channel number is not in the code, but it is on my ad manager on the AdSense site.

This is bad design, because I now have to create tons of identical ads (so basically many Units that look all the same), but with different Channel numbers associated to them, so I can track them correctly.

Or am I missing something here?

Thanks a lot
