Thanks for taking the time to reached out to us. I'm here to help provide some insights about updating bank feeds.
Currently, QuickBooks Online (QBO) doesn't have an option to update multiple banks feeds at one time. For the meantime, you can manually update your clients bank feeds one at a time. I can see how this feature would be helpful for you in order to update the bank feeds conveniently. You may want to submit this idea to our product developers so they'll be able to include this in their next product update.
