Pricing for Volume Clients versus All Clients

Hi.  So, we have a normal (sale) price for all customers, but - in some instances - we apply bulk discounts for customers who buy regualry and they have a pre-negotiated price.


It would be great if Products allowed us to pre-determine both the all customers price and the negotiated rate for this client (The margin field would then need to switch from calculating the margin based upon the specific customer price field).
