Dear Cindy,
That's a very interesting question.
It would require some additional Javascript coding specifically to your survey which could be done by using a dedicated External Module but this would then increase the risk of cyber attacks on the whole server.
As such, I am very sorry but this is not something that we plan to implement.
In the mean-time why not have simply a message before the button to inform users that they should wait 3 minutes before going to the "next page" ?
Best,
C.
