Viewing iPhoto videos by date in the Event Library pane

I really like the way that movie clips which are imported into iMovie are organised - by year, month etc - in the Event Library pane.

Is there a way of doing a similar thing with iPhoto videos displayed within iMovie? At the moment all my iPhoto videos in iMovie are just lumped in together and I have to scroll through 194 of them to find the one I want.

It would make much more sense to be able to filter them by year, month etc just like the iMovie clips themselves.
