Hi Ben,
Unfortunately there is now such possibility in ViArt Shop.
Nevertheless you can contact us via Support Form at

Is there an alternate way of making certain credit cards available from certain payment systems other that going to the static table for credit cards and deleting them globally?
For instance, I may have a merchant account that handles visa, mc but another that handles Amex and some of the other esoteric cards. Also, I hate to delete cards types that I may need later!
Thanks,
Ben
