If you are interested in Bulk Editing or Bulk Update of profile or status fields; this is a technique I have used and it works pretty slick. The person making the changes (usually the admin) will need to use the Executive tab to make these updates. Use a view showing all the projects you wish to update and start by editing the first project profile or status. As long as you are in this environment, you have the ability to edit, save, and then click on Next Project on the gray bar. This works pretty slick and I can go through my complete portfolio making updates very quickly.
