Open invite versus Challenge

When I look at the 'my games' page on the left are symbols next to each game that denotes either open invite or challenge.

Is there any way to tell who challenged who and whether I accepted someone else's open invite or vice versa?

When playing multiple games it can be hard to remember.

Edit

Yes, I know I could make a note but just wondered if there was an easier way.

No, as far as I know the infromation is not stored anywhere where it would be accesible to the user. (I doubt it is stored at all)
