Customise checkout page confirmation: "you can close this tab at any time"

[topmusictim]

Hi everyone

After some recent testing, I recently found out that my checkout confirmation page says: 

Thanks for using Paypal!

You can close this tab at any time.

This is unhelpful, because it auto redirects back to the thank you page on my site and I don't want people to close this page. 

Is there a way to change this to "please wait while you're redirected..." kind of message? 

See below for screenshot. 

Thanks, 

Tim.

What PayPal product are you actually using?
