Thumbs down from end user triggering LiveAgent / Log a ticket options ?

When a user click on thumb down, it triggers the comment “Thank you for submitting your feedback” 

Instead of that neutral sentence we would like the sentence to be adapted to the negative experience and that the bot produces something like this: “ Sorry my answer was not fully satisfactory.  Should you need further assistance you could either chat with a Live Agent or log a ticket.”  With the 2 action buttons being offered “Chat with LiveAgent” & “ Log a ticket”
