Following this thread as we have a similar issue.
My department works on a high volume of projects, many of which are loaded in bulk (though a kickstart) at the start of the product year. As other projects get added during the year, and as customers place pre-orders for products, projects get re-prioritized, and it's often necessary to push back task dates on less urgent projects.
I wish there were a middle-ground option for reflecting project status/condition between manual (too labor-intensive for our volume) and automatic (too rigid; doesn't account for changing priorities).
