Feature Request: MAP Pricing

I read the post about how to do a workaround, but would really like to see this as a feature in Hikashop. We have a client or two who MUST not advertise any of the normal products at anything less than a MAP (Minimum Advertised Price), EXCEPT in the shopping cart. If they use MAP, they are not price competitive on many, many items, which defeats the purpose of selling online.

For some business segments, this is a critical feature. Thanks.
