Deleting Magic Bullet looks effects on whole sequence

I have applied Magic Bullet Looks to whole sequence I have in my FCP X. But now I want to discard these effects and apply new ones. My question, is there a way of deleting effects I don't want anymore to whole sequence at once? I can do manually for each clip that that is hell of a work so I figure there has to be an another way.

Thanks!

Select all the clips in the timeline (Cmd + A) and in the Inspector, go to the Video Tab and delete the effect.
