What would stop you from concatenating the email addresses into a single field on the report via a sub-report?  You'll likely have to use variables and three formulas (e.g.  email_init, email_append, email_show) but once set up it is fairly clean.

On the PrintBoss side, I wouldn't be surprised if they didn't have a mechanism for handling that. In the past when I've had what I thought was odd request of PrintBoss I typically find out that it is in the software, just not documented.  So it might be worth a call to them.
