Hi
there isn’t really a simple way of doing this.
However, I understand that in some circumstances it might be somewhat tedious to do this manually.
Let me ask you something first though: How comfortable are you with writing/editing a little php script, as I could probabaly write a few lines of code you (and for the benefit of others) could adapt to make this a little simpler ?
i would/could put it into the codesnippet section for future use
