How to hide factor bank account created by mistake?

Summary:

A user has created a supplier bank account and ticked (by mistake) the factor account flag. Now this account is always showing up when we use Select and Add Supplier Bank account under (Supplier Site - Payment - Bank Account). The account is deactivated, but it still shows up under select & add bank account for any supplier on any business unit.

We would like to know, how we can make restriction so that this account is no longer visible under select & add page.
