sorry I don't but perhaps I should as I have several thousand!

I asked the admin people this several years ago (when they still showed some interest in GoY) and they told me it is not possible to do so. You will have to do them one by one. I gave up in the end.

Dont think so. Have to do so one at a time. I do a bit of Housekeeping bit at a time.

Luckily,I've deleted quite a few as I've gone along,over the years too.
