Imagine Ive used Pathauto to set a pattern for aliases, but then later (after creating nodes that used the first pattern) decided I want to change the pattern. My understanding is I have to delete all the aliases and then bulk create them again.

This is fine until ive individually set the path for a few pieces of content. As this 'manual' url is overridden, I need to remember to go back and change it. This could result in broken links and could even break a site.

Therefore I think there should be a way to update path auto patterns but leave individually (per node) set urls alone. Or the delete aliases function should have an option to not delete aliases that are set individually. Thanks
