Single post in Adopt a shelter Pokemon from its profile page

I'm half supporting this. Just like Raca said, if someone is realeasing, let's say a shiny pokemon, people could adopt it right there, without giving aanyone a chance. A positive for if you could adopt a shelter pokemon form Its profile page is that, let's say, I was in the shelter, when all of a sudden, There's two exclusive or legendary pokemon I need for the dex! But, I can only adopt one. But, if I had one's link, I could adopt one of the pokemon, and adopt the other after I adopt the first one. That would be very useful (And also because that ALWAYS happens to me)
