Websense Endpoint Package Builder - Trusted Sites Expression

All --

The Websense Endpoint Package Builder allows you to add trusted sites, but it only allows four lines (four regular expressions).  I thought there was a way to put multiple expressions on one line, but the documentation is severly lacking.  Anyone know what the parameters are behind this?  It's something like putting a semicolon in between entries on one line, or something like that.

Any help would be appreciated.

Thanks!
