You can add custom job variables to your job that can be used in rrEnv files or render config files.
Custom job variables options can be set
To use your custom option in an .rrEnv file or render config, simply use <CustomMyVariable> in the commandline
Important note:
Inside RR applications like rrSubmitter or rrControl, the variables are shown with their name like "myVariable".
Outside the RR application itself, like in any render config file, any submission .xml file or any commandline flag
you have to prepend "Custom" to the variable name: "CustomMyVariable"
