Youtube Dislike Button – to click in iMacros?

The other day Youtube had an update, and their buttons changed.

Can anyone figure out the code in iMacros (firefox) to Dislike a video that would work?

I tried all the recording modes. On regular recording mode the TAG POS=# changes all the time. On EVENT recording mode, the end result is imacros click on the LIKE button, not the DISLIKE button. I need to click the Dislike button.
