Create a notification on review (redirecting back to product info)

Hi, i have set my review page to redirect back to the Product Info page upon submition of a review as i prefer this idea to the default page that zen cart directs to.

However these occurs so fast it leaves the customer in doubt that the review has been submitted, especially as we will have the reviews requiring approval before being shown online.

Is there anyway to create a pop up associated with the 'Submit Review' button, saying 'Review submitted for aprroval many thanks blah blah blah' before the redirect occurs.

Or can i create my own message stack item and have it display once returned from the review submit option? I already have the message stack for 'Product Added To Cart' in place, can i create a message to appear in this position?
