Make item exempt from shopper group discount?

[heypachuco]

Hello,
I have a shopper group that will receive a 20% discount off all but one item, which we are only offering to this group.
This item has a MSRP of $29.99, but we are offering it to this shopper group at $19.99.
I've tried a price override of $19.99 for this item, but in the cart total there's a line for the shopper group discount (20%) even though it's not applied to this item.
This line does need to be visible though, as it would apply to any other items they may order.
I can't figure out a way to have this item priced properly in the shopping cart. Any suggestions are greatly appreciated.
Thanks.
