I would like to add the %author% structure tag to one of my custom post types that I've created via Custom Press. Is this possible? I've tested it out and it doesn't seem like it works. The output is /custom-post-type/%author%/ and not the actual author's name.
I'm wondering if I should use this plugin to get my fix but I don't know if it will cause a conflict with Custom Press: http://wordpress.org/extend/plugins/custom-post-type-permalinks/
