Thompson, that does sound a good idea, but presumably something else for hard-pressed local authorities to have to take responsibility for, and this is the UK - if **some** dog-owners can’t be arsed to pick up their dog’s poo and put it in a bin or take it home, I suspect they also couldn’t be arsed to walk by the designated poo-area for their dog to do its business. I could be wrong, of course, but that’s my strong suspicion.
