Hello @MrsLawson2221,
Welcome! Thanks for joining the PayPal Community Forum. This is a great question. I actually had to double-check this through sending money and checking out on a merchant site. Currently, the only way to change a backup funding source is through our checkout / send-money process.
Apologies for any inconvenience this may present,
- Jon K
