You can do this under RME > Config Mgmt > Config Editor > Config Files. Choose the option that says "External Location", choose the device you wish to deploy the configuration to and then select the configuration you wish to deploy from the shadow directory located under CSCOpx/files/rme/dcma. You need to actually select the configuration file as "Location" under "External Configuration File" ie. C:/Program Files/CSCOpx/files/rme/dcma/shadow/Switches_and_Hubs/PRIMARY/cr-nms-6506e.cfg. Then click on Edit and hit Deploy.
