Can I pass additional context to llm-cmd?

I can use my existing templates with the `llm` tool like this

```
llm -t my-custom-template "Do something with the context in my template"
```

But I am not able to do use this template with llm-cmd

```
llm -t my-custom-template cmd "Do something with the context in my template"

Usage: llm prompt [OPTIONS] [PROMPT]
Try 'llm prompt -h' for help.

Error: Got unexpected extra argument
```
