Set which payment methods for Prod./Cat.

-- url of the page with the problem -- : mywebsite.com/mypage
-- HikaShop version -- : 2.2.3
-- Joomla version -- : 3.1.5
-- PHP version -- : 5.3.23
-- Browser(s) name and version -- : XXXXX x.x.x
-- Error-message(debug-mod must be tuned on) -- : Error_message
I created 2 Authorize Payment Methods, one for Partner "A", one for Partner "B". They each have Auth. accounts
Is there a way to have 2 Authorize.net payment methods, but during checkout only the product/category related payment method will display, not both as is currently.
To limit confusion on checkout and to have the right one selected.

Or, can I set which payment method is default for the unique product or category.
