I think TTnScript is the way to go. You can dynamically add/remove events according to which "screen" you detect. If you don't use TTnScript, has a look at his source code to understand how to get hand on the input stream to chack for data.
I also uploaded a modified version of the components. It is a proposal of changes by John Porteous. It will probably appear shortly in the distribution.
