Make payments to NON special financing payments..

Description

How do I make NON special financing payments? I was wondering how to pay for my other transactions that are not part of the special financing. Is there a way to pay off those instead of it automatically deducting my payments from the special financing? My special financing ends in June and I wanted to keep that amount there until it gets closer. Every time I make a payment, the payment goes to the special financing instead of my other transactions.
