(Nearly) one click solution to remove all metadata of a photo

[neinei at gmx.net]

Hi there,
presumably I have overseen it somewhere but I am looking for a (nearly)
one-click solution in DigiKam to remove *all* metadata from a photo or
video file. This could be a single file, a file selection or all files
in an album.
Perhaps someone has a hint for me?

Thanks in advance,
