Business Unit Security

I am interested in implementing a business unit security model in E1 9.1/9.1 that is similar to the business unit security in World.  I found the document 'E1: SEC: How to Setup Business Unit Security in EnterpriseOne Similar to World Software' which describes how to do this for a specific value or range of values.   In my environment our business units (alias MCU) start with a two character prefix and then have a four digit number (e.g. GT1234, MR2231, SV0070).  Is there a way to set up this type of security for all business units that start with GT for a specific role?
