Private Communications with Team members in a task/project (not guest)

Hi,

One of the main features lacking Asana is the ability to have internal communication/ feedback with internal members (as a group or individual) without Everyone being able to see the message.

I would like for instance my supervisor to provide internal feedback for me on the tasks/ project without having everyone’s access to that conversation.

Right now I created a separate project called internal feedback with specific members but this is not ideal as my supervisor cannot comment on a specific task or project.

Thanks
