Sprite rect outside of viewport of Sprite Editor

I have a sprite sheet that I spliced into several sprites. I then removed some of the sprites from the actual sprite sheet image and so some of the sprite rects from the sprite editor are outside the texture/image now. What I’m trying to do is delete those sprites/rects that are now outside the image. I’m able to delete a few but the others are now too far away and I can’t zoom out far enough to see and delete them in the sprite editor.
