Why can't I choose what type of ball my dudes are in AFTER I've caught them?

At least when breeding I used to know they would all end up in regular Pokeballs. Adding into the equation of making all of their balls matching from catching/breeding is so annoying.

"Here Scyther, let's try this one out for a while"
>Scyther is now in 'SAFARI BALL'

Easy enough Gamefreak.

What the fuck?
