I have two printers and Acrobat Distiller. Every time I print, a dialog box gives me the choice of which printer to send to--the Default printer, or one of the others. One click, done.
ACT! designates <Contact> as the merge field... but why not make that field switchable or multiple/more than one?
In my application, it's better for me to have one record per company, AND to be able to reach several persons or alternate persons within that company via a mail-merge (email, letter, etc.). Switchable or multiple/more than one would save me time copying/pasting/sending.
