I am trying to use this plugin to extend the concepts of the existing permalinks ('pseudo-permalinks' ?).
For instance, when I recognize a build over some others (you might say promotion), I would like to provide a 'lastSuccessful<moniker>' and/or 'last<moniker>' alias(es) for the build.

The problem is that when I recognize the next build, and I want to 'move' the pseudo-permalink to point to the new build. However, the list of aliases keeps growing with duplicates, and the actual alias url can only point to the first build.

The Enhancement I'm proposing is to automatically detect when an alias is already assigned to an earlier build, and then do some housekeeping to make sure the alias url, is now pointing to the latest build carrying this alias.
