iTunes no longers asks "Do you want to keep the original file or move to trash?" - Can this be fixed?

I'm not sure if this was a recent update in Mavericks, but when I used to delete items from iTunes it would ask something along the lines of:

Do you want to keep the original file or move to trash?

Now I no longer get this, instead iTunes asks:

Are you sure you want to delete the selected song from your iTunes library?

After which, if you choose the option "Delete Song", you get no option to keep the original file, it just straight up deletes if from my library and hard drive. Does anyone know if there is a way around this? For whatever reason, I want to be able to keep the original file on my Mac, without keeping it in my iTunes library.

I've tried resetting dialogue warning, and this hasn't made a difference.

Thanks!
