Option to Exclude Customer Type From Deal

We are using B2B Portal as well as selling retail on DEAR and DEAR POS.

We have a number of Deals that would apply to all DEAR POS and DEAR customers, except our B2B customers who already get special pricing. Currently we can only really set them to DEAR POS sales.

Every time we make a  new customer the discounts won't work automatically in DEAR, unless we were to go to the customer and add a tag, or go to the deal and add the customer which is too time consuming.

Would be great to have the option to exclude B2B from the deal, but have it apply to everyone else.
