Can I change the User_Input in the Agent Node of the Prompts Library?

Can I modify the User_Input in the Agent Node of the Prompts Library?

I want to apply the User_Input in the Agent Node of the Prompts Library to a modified User_Input.

For example, if the user inputs “save” I want to change it to “file save” and have it be applied to the prompt and executed.

i want to save this → i want to file save this

        {
            "role": "user",
            "content": "i want to save"
        }


{
“role”: “user”,
“content”: “i want to file save this”
}

Please tell me how to do this.
