SUGGESTION: Allow Sale Codes to apply to Individual Resources

I realize that many of the sales Logos offers are finely tuned agreements with the publishers, and no doubt some are predicated on preset objectives. Sales offered on collections, such as the current one, may be dependent on the concept of the collection as a whole. However, I'm not interested in the collection as a whole, just one resource within the collection. If I could apply the sale code to that single item, I would get it. Unfortunately, I cannot. Logos ought to consider making such codes operative for individual items that make up the collections on sale.
