Setting cookies (or headers in general) from `createServerData$`
Is it possible to set cookies (or any other headers) from the fetcher passed to createServerData$? I have the following code: 
export function routeData() {
  const user = createServerData$(async (_, { request }) => {
    const client = await createAuthenticatedClient(request);

    return client.request<MeQuery>(gql`
      // ...
    `);
  });

  const success = createServerData$(async (_, { request }) => {
    const session = await getSession(request);

    return session.get('success');
  });

  return { user, success };
}
export function routeData() {
  const user = createServerData$(async (_, { request }) => {
    const client = await createAuthenticatedClient(request);

    return client.request<MeQuery>(gql`
      // ...
    `);
  });

  const success = createServerData$(async (_, { request }) => {
    const session = await getSession(request);

    return session.get('success');
  });

  return { user, success };
}
getSession is just a wrapper around the cookie session storage that's built in to solid-start. When I call useRouteData<typeof routeData>() in my component I can get success from the session. success was set on a previous route as such: 
  session.flash('success', 'Your email has been verified!');

  return redirect('/', {
    headers: { 'Set-Cookie': await storage.commitSession(session) },
  });
  session.flash('success', 'Your email has been verified!');

  return redirect('/', {
    headers: { 'Set-Cookie': await storage.commitSession(session) },
  });
Now I would like to commit the session with the flash message deleted. How can I do this from within createServerData$? It doesn't seem that I'm able to return a Response or anything like that, and redirect wouldn't make sense either.
