Good morning, @johnpc58. 

I hope you're enjoying this beautiful Monday. 

You can set up an asset investment account in your chart of accounts. Below I've included the steps to do this. However, in QuickBooks Online, you won't be able to connect a bank account to an asset account. The only account available to connect to would be a bank account type. If you'd like, I can submit feedback to our product engineers, so this could be considered in a future update. 

Let's set up your asset investment account:

1. Open the Accounting menu and choose Chart of Accounts. 

2. Select the New button in the top-right. 

3. Then choose your account type (Asset). Pick your detail type (Investments) and Save and Close when you're finished. 

That's all there is to it. In the meantime, you can check out Add an account to your chart of accounts in QuickBooks Online for more details on adding accounts. 

Please let me know if there is anything else that I could assist you with. I'll be here for you every step of the way. You can always reach out to us here in the Community anytime you find you have questions or concerns. Take care and have a good one!
