I have custom config addon set up and it contains some info already, entered on the addon deployment phase using following syntax (https://www.cloudcontrol.com/dev-center/Add-on%20Documentation/Deployment/Custom%20Config):
$ cctrlapp APP_NAME/DEP_NAME addon.add config.free --PARAMETER_NAME=PARAMETER_VALUE
I'm wondering if there s a way how to update config in order to add (or remove) additional key/value pairs without removing whole addon and adding it again with the old code?
