OK. I’ll give it a try. And I agree the best solution is ALWAYS to record all three modes. Don’t know why I thought this would work. Lesson Learned.

All depends on the length and type of the demo. It is indeed possible, but you’ll have to add one interactive object on each slide. For a ‘click’ action that will be a click box, eventually accompanied by a highlight box. You define the number of attempts and the Success action is automatically set to Go to Next Slide which is fine. The default Training sim has infinite attempts for click boxes, but I find that very frustrating, and always limit it to 2-3 attempts, where I set the Last Attempt also to ‘Go to Next Slide’.
For a typing action it is bit more complicated: you have to delete the typing object from the slide, replace it by a TEB, and set the Properties for the TEB. More work, but if the number of slides where the learner has to enter text is limited, probably less work than recording.
Just a tip: I ALWAYS record a software simulation immediately in the 3 modes. Much easier to delete a file, than to do the editing I just described.
