WebI Outer Join across two Universes

Hello,

Could someone point me to a tutorial showing how I might accomplish this SQL query in Web intelligence.  My problem is that the two 'tables' in my query are from two different Universes.

SELECT A.AccountID,A.AccountName,A.AccountStatus from Table1 A left outer join Table2 B on A.AccountID = B.AccountID where B.AccountID is null.

I don't have rights to access anything but building reports in Web Intelligence.  I can't seem to find the magic Google key words to get any good answers.

Web Intelligence Version 4.1 build 14.1.6.1805

Thanks for your help.
