Sorting comments not replied to column by date recieved

I love this plugin but the one thing that is frustrating is that the comments not replied to column isn’t sortable. Right now it’s always the most recent comment first and I’d like to be able to sort it so that the oldest unanswered comment (since plugin activation that is) appears first. Might this be possible in an update?
