B2B Portal Guest Access

We allow "Guest Access" to our B2B Portal so that potential customers can find us on a Google Search for parts.  We don't want them seeing prices unless they have a login, so we have set the Price Tier for Guest User to a tier without pricing.  

However this means that the price shows "$0.00".  We would like a setting where we can display the words "Login for Pricing" instead?

Thanks.
