Please, can you make it so that you can set up a promo to be used on more than one item.
i.e. To make a promo (without a code), so that when a customer buys a hosting plan of X, Y or Z, the domain they are purchasing can be free (or discounted) if it is either a .com or .co.uk or .uk or me.uk or .co.nl, etc.

Currently, the choice seems to be, choose one TLD or all TLDs (group).

If the selection box for the product/service to be offered at discount/free were to be made the same multi select box, then you could select those that should be included in the promotion and if they select one of those TLDs then they would receive the discount.
