Payment methods in Admin Area

Hello Gentlemen, I need your help. I have two types of shipping methods (post office and pickup point courier). Every payment method connected to that pickup point courier must have following text

[[Z…:connect-field=#branch_name_street country=…]]

in the description. So you can choose your pickup place in the order. The problem is with the payment modules (Credit card,Paypal). Is there any way how to have this condition only in shipping method “pickup point courier”. If I put that text

[[Z…:connect-field=#branch_name_street country=…]]

to the description of Paypal or Credit card pament method it is also displayed in shipping method post office.
