Edit a Forum topic page. to include replying to a comment inline with the remainder of the thread?

Hello! First time Lithium user and designer. I want to make some changes to Lithium, in the default template so that when someone replies to a specific comment in a thread, that reply is inline with the remainder of the thread.... sort of like how you would have a reply-to, but instead of going to a whole seperate page, I want it to be inside of the comment thread.

Is this somethign that I would do in the custom layout of that specific page in the lithium studio?

Thanks!
Josh
