Unfortunately your question concerns two products I have never used before :(
Is there any string within the ASP URL that can be used to define which page of your site that you are on ?
If so then there is a section in the Webtrends manual - Tracking Internet Advertising - that may be able to give you what you require. You can use the text of the url to identify the page and then assign it a more meaningful name. This may work if you only have a small number of unique pages, however if you have many hundreds it would soon become an administrative nightmare.
