Is is possible to open sprite in external editor?

Hi it would be super if i could open sprite in external image editor, do some adjustements and save the file , and reload the scene and the sprite will update . is there a way to do this? Or do i have to edit the sprite say in paint net, and then start building the level from scratch with this modified sprite?
