Exclusion of certain products in order total discounts

An opportunity to exclude certain products from a discount would be very nice. Right now we have the possibility to create discounts on single products, and I expect multi product discounts (by taxonomy or admin multi product selection) will be implemented in the future. However the opposite way to work is also important. I would definitely like to exclude my sale items from the order total discount I offer my customers as an introduction offer.

This could be done by taxonomy (since I have a special class for sale items) or by comparing List price to Sell price (excluding allready rebated products), or by admin multi product selection (though preferably not this last alternative).

This way a store could work both with substantial sales, and with discounts for certain users on the non-sale products. Right now I cannot put a low price on sale items as it would make me sell at loss to users qualified for a discount. I need these selling tools to work in a coordinated way.

So, anyone else in need for product exclusion in coupon discounts?

Kind regards,
