Company ID and Company Name in SmartList Builder

Hello:

I have always known that the only way to get a "global" SmartList of data across all companies is to write a SQL "UNION ALL" script.  I see that SmartList Builder has a "Company ID" and "Company Name" fields.  But, those are only valid for the GP company that you're logged into.

Am I correct or incorrect, on both of my thoughts on obtaining "global" data?

Thanks!
