Is it possible to add a Read more to really long comments?

When i first was testing this out I noticed if I posted a really long comment it would be cut off according to the settings for the plug-in. When it cuts it off though there is no way to read the rest of the comment. What i was wondering if we can implement some kind of Read more for the comments themselves so you could show a certain amount of the comment by default then if the comment was longer then that and you wanted to read it you could click Read more and open up the full comment.

Right now once the comment is cut off, there is no way i can see to view the entire comment.

I'm using the Modern Template and JoComment 4.0 beta1. Joomla 1.5.14
