Most websiters/webapps update their url based on what page you're on (even if you're 'loading' another page).
So you load the tool, and click on an asset. I would then expect the url to update to domainforda.com/asset/assetid
When you then click to edit the asset: domainforda.com/assets/assetid/edit
etc
the advantage of implementing as well is that it fixes the current navigation problem where you can't use back/forward buttons in the browser and on your keyboard to quickly navigate between screens
