How do I bulk change a split transaction?

My paycheck (every 2 weeks) is split up into different transactions. Is there a way I can take all my paychecks this year and change a single transaction? It's actually a transfer from one account to another. For example $100 every paycheck is going to account A but I want to change it to account B. My paycheck is a scheduled transaction so I know how to change it for future use.
