Lucas got before me (I found a colleague with some insights to the matter during my lunch...)
Apart from external triggering (to some property of an Calc or controller signal) you can also use internal triggering with the help of e.g. the _NOW variable and some simple math, e.g. modulo (%).
Its not a common solution but is should work...
You can use the Aspect View Invoker in PG2 to create a sequence of screens.
You need to prepare a variable on the controller (toggle the variable) an connect the variable to the Trigger of the Aspect view invoker. On each screen you need this Aspect View Invoker to set a trigger to jump to the next screen (ViewReference).
