Mail merge using 2 data sources in 1 document

[Red Five]

Hi there,

I am trying to create a template for a letter which has two separate
"contacts" ie the person the letter is to, and the person the letter
is in reference to. I would like to use one database to fill in the
merge information for the recipient, and another database to fill in
merge information for the "topic" person. Is it possible to create and
use two databases in the same letter this way?

Thanks!
