Cs Cart Specific Price Per User Group

Is it possible to add second price to each product and use that price if user in specific usergroup?

I was thinking doing that by adding another column to the product price table and then take advantage of the promotion function to somehow use that price instead of the usual discount you can set from admin.

Any pointers or ideas would be great, thank you.

You can use the built-in Quantity discounts feature to specify unique prices for usergroups:
