Setting default values for commands

Hi.
I want to set default values when creating a command like here:

object CheckCommand "ftp" {
    import "plugin-check-command"
    command = [ PluginDir + "/check_ftp" ]
    timeout = 1m
    arguments += {
        [...]
    }
    vars.check_address = {
        arguments = [  ]
        deprecated = false
        type = "Function"
    }
    vars.check_ipv4 = "$ftp_ipv4$"
    vars.check_ipv6 = "$ftp_ipv6$"
    vars.ftp_address = "$check_address$"
    vars.ftp_mismatch = "warn"
    vars.ftp_ssl = false
    vars.ftp_timeout = 10
}

I can’t see though how to set these values in a custom command via director. Could pls. someone push me to the right direction?!

After you defined the arguments add corresponding fields to the command and then on the command tab itself you can use the fields to add default values.
