Sure, that's one way of resolving it - perhaps I'm too cautious.
A suggestion on another way of indicating new objects in a project. A page template that shows all new images, or if none within the timeframe set the nth most recent. Thumbnails link to the image and/or the subfolder they are within. An advantage is all new images can be seen regardless of how deep they are in an album.
I have such a template but it won’t work with recent Tiger versions, it reports parsing errors that don’t exist.
