LS9 Granting Access to a Range of Company or Process Levels

I am trying to write rules in LS9 for granting access to a range of companies or process levels.  An example would be 1000 to 1299 and 4000 to 5999.  And oh by the way I need access to company 15 too. ProcessLevelControl and CompanyCompany in RM only accept values like 1000, 1001, 1002, etc.  It would not be practical to load up all of those values in that method. I can't find any documentation on ProcessLevelControl or CompanyControl in any of the Lawson manual or Inforxtreme to confirm the acceptable values.  Is there any other field in RM that may allow me to write rules for ranges?
