Different colors for page icon depending on part of the web site

I am already using goals but I am missing the possibility to see immediately on the live/detailed visitor log in which section of the site a visitor is now - on the landing page, on one of the documentation pages, in the store, using the product demos, on one of the blog posts etc. So it would be very helpful if I could define sections similar to the goals - as URL segments or regular expressions - and assign colors to them. The colors would be used for the page icons so that I could immediately see in which part of the site a visitor is now and understand the transitions.
