I have an app which posts a message like this to a user's Facebook timeline:

This is working fine, but if I post a few times, my posts get grouped on my news feed, and I get this:

What settings should I use to control the way this news report appears? Instead of 'All about periods' and the page link in the box at the top, I'd like 'Body iQ Quiz' and the app description. Where would I set these values?

And is it possible to make the grouped report say 'Jay cee Effex shared a link via Body iQ Quiz', the way the original post does?

I'm posting from the Facebook AS3 API, and my post code looks like this:

var auth:FacebookAuthResponse = Facebook.getAuthResponse();
var token:String = auth.accessToken;
var user:String = auth.uid;
var values:Object = 
{ 
    access_token: token,
    name: "Body iQ Quiz",
    picture: "http://a7.sphotos.ak.fbcdn.net/hphotos-ak-snc6/282950_427728213914009_630526316_n.jpg",
    link:"http://www.lil-lets.co.uk/en-GB/Wellbeing",  
    description: "Women, how well do we know our bodies? Click here to find out what your Body iQ is.", 
    message: result.FacebookBody + " " + result.FacebookTitle
};

Facebook.api("/" + user + "/feed", handleSubmitFeed, values, URLRequestMethod.POST); 

... but I'm not sure if this is something I can fix in code, or if the app configuration needs tweaking?

NOTE: Some users report getting the latter format in their news feed even with a single post (I can't reproduce this), so perhaps grouping is a red herring, and the real question is how to format the news feed report of a timeline post?
