Being able to view Routing Line Comments in the routing page (Page design)

I would like to create a new Routing page similar to the one that comes with NAV 2013 out of the box, only with the following change;

Underneath the Lines list, I want to have a Routing Line Comments list which shows the comments for the selected routing line. It would be great if I could use this to edit the routing comments too.

How do I do this. I tried, but it did not link to the currently selected routing line.

Is there a way to do this?
