Could we get the option to add a personal note/comment by names in our friend list, sometime down the road?

Sharing various events with random players often end up with a new name on the list, as do helping people/recieving help with melds etc. But in hindsight it's often hard to remember who the different names on the list are - who was the person who offered to help with future raids? Who was the person met during bored downtime and joined for an hourlong session of manderville dancing in Ul'dah? And who the heck was that guy?
