There is no “super saver day pass”, you either got a supersaver ticket or a saver day pass.
So based on your question, I would rather guess you got the latter one. Because supersaver tickets are the only ones actually tied to a particular train, so therefore that specific train would be mentioned on the ticket document.
So with saver day passes or regular tickets, there is no need to ‘transfer’ (whatever you meant by that) the ticket to a train, as the ticket/pass is valid on any train on that route during the entire day. The ticket is nothing more than a proof that you are entitled to get from St. Moritz to ZRH on whatever train that day, and that you already paid for that service. Probably quite comparable to a subway ticket (or day pass) in your country.
