How to render a optional and drop node name command using clispec

I am interested to create a new command under existing command via clispec.
For example: Following is existing cli command.
login-banner inline message
I need to have eof-marker after login-banner inline message
Here eof-marker should not be displayed in cli. It should accept any string and it is optional.
Such as:
login-banner inline message ?
Enter eof
login-banner inline message customEOF
customEOF is the string entered by user.
I see that cmd in clispec takes name as an argument. Is there any way to drop name of this cmd?
In param, i am not giving name, it is fine there. Please suggest.
