Defaulting Content-Type

[M35a2]

Question:
Is there a setting or a way I can add default headers that are visible when sending a request in an API Playground?

Background:
In my OpenAPI spec, a header for Content-Type: application/json is required for all Post's and Put's.
In the examples, it correctly shows needing the header:

However, when running/testing the api call, the user has to add this manually for each Post and Put.

I can force it to happen, similar to adding an authentication header like this:

const plugins = [
    {
      getIdentities: async (context) => [
        {
          id: "auth",
          label: "Authentication",
          authorizeRequest: async (request) => {
            const token = await context.authentication?.getAccessToken();
            if (!token) {
              throw new Error("No authentication token available");
            }
            request.headers.set("Authorization", `Bearer ${token}`);
            
            // Automatically set Content-Type header for POST, PUT, PATCH requests
            const method = request.method?.toUpperCase();
            if (method === 'POST' || method === 'PUT' || method === 'PATCH') {
              // Only set if not already set
              if (!request.headers.has("Content-Type")) {
                request.headers.set("Content-Type", "application/json");
              }
            }
            
            return request;
          },
        },
      ],
    },
  ] as const

export default plugins;

However, while that does add the header, it hides it from the user, I would rather have it added and shown to the user in the UI to better help them.

I imagine there is already a built-in way to do this, but im not finding it in the documentation or here in GitHub.
If it doesn't exist, i think it would be a helpful setting to have. Where it can either populate the required headers from the API spec, or be over-ridden by a zudoku setting.
