Can't be done directly on the Update Stream (I believe), but you can create an alternate view of the Update Stream using an embedded dashboard in your Project view, which would contain a Notes report. The notes report can show the parent task.
- Create a Notes Report. (filter is "Note Text is not blank - no other filters needed)
- Add this column of text mode to your notes report:
displayname=Parent
linkedname=task
namekey=view.relatedcolumn
namekeyargkey.0=task
namekeyargkey.1=parent:name
querysort=task:parent:name
textmode=true
valuefield=task:parent:name
valueformat=HTML
- Add the Notes Report to a new Dashboard, "Notes"
- Update the Layout Template options (or, achieve this manually on a per user basis by selecting the "Customize Tabs" option under "More" when viewing any project). You want to add your new Notes dashboard for users in the "Viewing a Project" tab options.
- Now, anytime you view any project, you will have a new tab called "Notes." It will display your notes report, and it will only show updates that were entered on the project that is being viewed.
- In addition to displaying your Parent Task column, you will want to invest some time in adding other columns and making it a nice report. The Updates Stream offers a lot of detail, so this approach to just get the parent task isn't great - you'll want to add more detail to your report. Attached is a screen capture of what we have done using this approach (with a lot of text mode applied). In fact, I will probably update our view. The one shown is a universal Notes view available in our system, but I think I will tailor this particular report to exclude Project and User, and add in Parent Task.
Good luck!
