can we add doc_string from step definition(.java) instead of feature file?

I got the impression this wasn't a feature request but rather a "How do I do x" disguised as one.

To attach data

package io.cucumber.examples.java;

import io.cucumber.java.Before;
import io.cucumber.java.Scenario;
import io.cucumber.java.en.Given;

public class RpnCalculatorSteps {

    private Scenario scenario;

    @Before
    public void after(Scenario scenario) {
        this.scenario = scenario;
    }
    
    @Given("I log some data")
    public void log_some_data(){
        scenario.attach("{hello:\"World\"}", "application/json", "hell-world.json");
    }
}

This then shows up in the report as:

{hello:"World"}
