[Trinidad] Possible to skip certain stops in a train model?

[Phuu Tek]

Hi,

I am looking at implementing my own custom Train Model using my custom
ProcessMenuModel

public ProcessMenuModel getTrainModel() {

}

However, I have a specific use case wherein I should be able to skip
certain stops in my train.
Say for example, I have seven stops then on Step 2, I choose something from
that page.
Is it possible to disable Steps 3 and 4 programatically so that user wont
be able to navigate to that page?
Step 5, 6 and 7 should still be available.

Thanks
