OPTION 1
Using the Silverlight Console:
1. Create an Organisational view / Org Group
2. Filter names, and statuses as best you can, then drag them into your new Org View / Org Group
3. Once they are all in there then you can highlight them all and using right click assign them the new status, or use Bulk Edit function
OPTION 2
- Otherwise as Igor already said use ctrl click, shift click to select them all
OPTION 3
- Otherwise you can do a CMDB import, that will take you a good 90 minutes of pissing around creating Excel workbooks, import tasks, testing, etc, so probably not worth it but you'll have to decide on your best use of time...
- I try and get interns, and students to do stuff like this, they can update comments fields, and locations, status, etc at the same time.
