B2B2C Lists to Hide Pricing or Add Markup

As a distributor I'd like to be able to create custom lists for my clients where I can choose to show MSRP, MAP, or pricing with a markup on it. I'd like this functionality to be an option on a per list basis and updated when I'm creating the list.

Some additional thoughts on this is that the site can remain restricted if applicable, and the business' that use the site (who do have access to actually shop the site) can create 'shoppable guest lists' with configurable pricing (since the recipient is unknown and would otherwise just show either no price or guest pricing if loaded)
