So coming in a release that is expect very soon. Possibly next Friday to DEV (perhaps the week after) is this functionality:
So you add a new field and select the type of "Asset Path", but instead of bring back the full path separated by ">", you will be able to select to "List Single Segment" and select the level of the path you want to display. This is now listable!!
You can repeat that process as many times as you need and remember that you can make fields listable without even having to display them on the detail page. So you could display the full path on the detail page and have it broken out in the list view. Loads of options to play with to give you users a great experience.
Very excited about this one!
(as a side note and as a cherry on top of the Cake the dev have added the ability to define a sort order to the configuration menu too. Great if you use Auto-numbering and want to show the latest records first)
