Is there a way for BillPay to default to a specific bank account based on the Expense account in the bill?

Good morning, @treasurer180. 

Welcome to the Community! 

I can see how beneficial this could be for you and your business. However, there isn't a default available for bank account in Bill Pay. 

We recommend submitting feedback to our Product Developers so they can consider adding this in the near future. Here's how: 

1. Go to the Gear icon in the top right-hand corner. 
2. Press the Feedback option. 
3. Enter your suggestions. 
4. Tap Next to submit them. 

Feel free to reach back out if you have any other concerns. Have a wonderful day!
