Is there an option for something similar to the Other Names List from Quickbooks Desktop on Quickbooks Online?

I know on the desktop version is there is an option for "other names' instead of putting the Payee in as a vendor. Is that an option for the online version?

unfortunately, there is no way to add "Other Names List" in QBO. If it's money out, it's only Vendor type in QBO.
