Which version are you using? It will be less cumbersome in the latest version, because you can copy/paste decisions.
You can have a look at this blog post, it is not cycling text containers (which will be your case) but images. The logic is the same, bit different from Rod's explanation because I'm resetting the counter to 0 after each cycle. That way you need only one user variable (I'm trying to limit work). Probably you will not want to show an extra button after the first cycle, but that is easy to skip.
