A+ change verbiage on confirmation popup window and choose page after clicking ok


Is there a way to change the verbiage on the popup confirmation window. Currently it says:

"We have received your appointment. Thanks!"

I would like to change it to say:

"We have received your appointment. Thanks! A confirmation email will be mailed to you shortly."

Additionally, is there a way to choose/change which page hitting the 'OK' button directs you to? currently, it just refreshes the booking page. I would like it to take a person to another page on the site.
