Firebird connection missing a "Role" parameter

I have built-in change tracking on my Firebird tables so that I can know which user made changes to tables. I’d like to get ScriptCase 8.1.003 to use it’s own role, so that I can know if ScriptCase changed a field value. At the moment, there is no “Role” parameter in the Firebird connection, so that forces me to always use SYSDBA as the user for ScriptCase. How do I add the Role parameter to the connection, and if that’s not possible, will you be making a new version of ScriptCase that allows me to enter a Role for Firebird connections?
