Where can I find a place to create a 2nd Quickbooks Self Employed account? When I log in, I can't find anywhere to allow me to create a 2nd account.

I have 2 businesses, each with their own bank account and credit card. I'd like to have 2 Quickbooks Self Employed accounts to track each (and keep them separate). Ideally, with the same username where I can switch between accounts easily. Bonus would allow me to switch back and forth on my iPhone (where I track milage).
