Hello,
we added this to the "wish-list", but i think this has lower priority, because i don´t think that so much people would use it. At the moment you could write us a private message when you want to comment on an issue, and we get almost no private messages about issues.
I also think that not much people even look into MyIssues

, so i think it is not really necessary to have such a feature.
Best regards
