In the dashboard, there is a nice widget that shows 'Bank Accounts' Is there a way for me to customize it to show additional accounts (sub-accounts specifically)? How?

Hello there, gans.

The option to customize the BANK ACCOUNTS widget is unavailable in QuickBooks. However, we can pull up the data of the sub -accounts by running the report. Let me guide you how:

1. From the Accounting tab, select Chart of Accounts.
2. Locate the sub-account.
3. Under ACTION, click the Account history drop-down.
4. Click Run report.

If you want to add or remove some filter on the report, you can customize it. Here's an article as your guide: Customise reports in QuickBooks Online.

I'm just around if ever you need help. Keep safe!
