My b2evolution Version: 1.8.x

My last post made me think of this too. It is not so important, but would be nice.

I get two different permanent URLs depending on how I get to a page and they look like this:
http://ray.tomes.biz/b2/index.php/a/2007/05/22/p140 and
http://ray.tomes.biz/b2/index.php/a/2007/05/22/mayan_2012_prophecies_and_the_increasing

I get the second one from the permalink entry on a page and that is what google mostly uses to index pages. The first one is used by the "index of all posts" link in my sidebar which I think Yabba told me how to install. I wonder if there is an easy way to make the permalink entry on each page also make the shorter name? There are advantages to this because I operate an index to all my articles outside the blog also and I make this by manipulating the "index of all posts" html code.
