Group pricing - show discount

On our ZenCart installation, we have group pricing setup to give a 20% discount to a particular group of potential clients that access the site off of a banner link from a partner site. We use the "grpid=#" link to put the potential clients into the correct group.
This all works fine. But the client sees the shop items at the normal price UNTILL they get to the checkout where the discount is applied, is there a way so that the customers see the items listed WITH the discount already applied.?

Many Thanks
Steve

This could be customized using the display price function with some adaption to it to account for the discount and that would manage most all of the display prices except the shopping cart ...

It would take some work, but it could be done ...
