I'd check with the KC about this - I thought only the owner of a registered affix could use it at the front of the name and if it was necessary to add it to a buy-in puppy, it would be at the end after 'with', 'to', 'for', 'by' and so on.
The Activity Register wasn't around when I was 'active' LOL. So it may well be possible to use a registered affix first.
