Help modifying the Import to Selected Group and Delete script

Returning to this, I’ve just changed computers and would like to reattach the Import to Selected Group and Delete script to a desktop folder. It’s one of my favourite little Devonthink actions and I use it daily.

It doesn’t appear under the options I’m given in Folder Actions Setup – the closest thing is Import to Selected Group. As far as I can remember I first obtained the script from this thread post a few years ago, but the zip file in that post can’t be downloaded anymore. I had thought that this was absorbed as a formal DT script, but perhaps I was wrong? I can’t seem to find it. Can someone point me in the right direction?
