How can I add a non-bank account (specifically an Asset account) to the list of BANK ACCOUNTS in QBO Dashboard (Business overview tab)?

I keep a substantial amount of money in a deposit account at the U.S. Patent and Trademark Office (USPTO), which I use to pay patent office official fees when I file patent applications for clients. It is critical that I maintain sufficient funds in this deposit account, because otherwise I might not be able to pay a fee by its due date and, thereby, lose a client’s rights. Replenishing the deposit account can day days. 

Thus, I need to keep a close day-to-day eye on the amount of money in this USPTO deposit account, more so than even my bank or credit card balances. The QBO Dashboard is ideal for monitoring these balances. In QBO, I could characterize the USPTO deposit account as a bank to get the deposit account to appear in the Dashboard, but that would not be entirely accurate, especially for tax purposes. The USPTO is not a bank. It does not pay interest or issue 1099-INT statements. I suspect my accountant would object to listing the USPTO deposit account as a bank. 

How can I add a non-bank account (specifically an Asset type account) to the QBO Dashboard, ideally in the BANK ACCOUNTS portion, or alternatively somewhere else on the Dashboard?
