We can do this right now! It is a feature that may be enabled or disabled for any given poll question.
You can use our Custom Reply Message feature to send a confirmation message that a response was successful (our default) OR customize the message to say whatever you want, including links!
This feature can be found by opening the poll configuration page > select Response Settings > and enter your Custom Reply Message.
