Is there a way to filter comments by user in activity dashboard?

In one’s activity dashboard, gitlab.com/dashboard/activity, there is a panel about comments in stared projects. this is a screen shot of mine. (I hide some information to protect privacy as this is an internal project)

Since the administrator user is used as a robot in our project, so its comments are meaningless, is there a way to filter the comments so that all comments of the @root user will not be shown?
