Master login for multiple accounts

I manage several companies in Quickbooks Desktop. I am the only user. There are relationships between the companies, so it is necessary to switch back and forth between them to complete entries. It is massively frustrating to have to continuously log in from company to company. How can I set a SINGLE login so that once I am in a Quickbooks session, I can switch from company to company without having to literally restart the process every time? Huge waste of time.
