Can not change images without loosing all focus points

[maikschneider]

Sometimes I need to change an image in an existing manual. When I want to do this for an image in the "Focus Point" content element, all used focus points are removed. I need to add create all squares, type selctions, titles and descriptions again. Is there a better way preserve this focus point "meta data"?

A workaround is to replace the exact same image in the fileadmin using the exact same filename etc... But this is a impractical workflow.
