I think we're both misunderstanding.
I have four eBay accounts.
Two different types of Paypal.
Two of the eBay selling account IDs should be on one key as to the type PP account I have.
The other two eBay selling account IDs should be on another key as to the type of PP account they are.
Two totally different types of PP and four different eBay IDs doing business with what type of PP suits the sales.
Hope this helps.
