Financial Reporter Account Reference Syntax


Ok Financial Reporter gurus. I cant figure out the correct syntax for account references with multiple segments. I have a client with an account segment that use 3 segments. I want to select a range of accounts that can filter on the 3rd segment. 

For example accounts 1000-100-01, 1000-100-02 and 1000-100-03. I want to select a range that includes ALL of the first 2 segments but only 02-03 of the third segment. I cannot get it to work. Is there a way to use column B instead to exclude a specific segment code?
