Automatic MS_RFDIR Creation

I am working on a major revision to our network workspace and am trying to build the MS_RFDIR configuration variable with our knowing all of the possible directories that will need to be included. 

I have a base set of directories to include in this variable but some of our design build projects have additional directories that need to be added as the project progresses.  I don't know the directory names until the files are recieved from another design firm and I don't want to continually edit the PCF to add the new directories

Example:

Base Directory:  /DesignBuild/

                      /DesignBuild/CompanyA/  #Additional subdirectory added after creation of pcf file

                      /DesignBuild/CompanyB/  #Additional subdirectory added after creation of pcf file

 

Is there a way to have all subdirectories(CompanyA and CompanyB) of a known directory (DesignBuild) added automatcially to the MS_RFDIR without using VBA or another other programming language?

 

Thanks,
