Single post in Pokeballs

I'd support this without any EXP bonuses, because there's already enough ways to earn EXP. I think the Fishing hut is a nice way to implement this, though on the other hand I feel that the existing Pokeballs are enough function-wise (i.e. a great ball may not be needed if there's a fishing great ball). But I'd be interested in all the designs of other Pokeballs such as the Master Ball, and I'd also be interested in putting Pokemon in them (or at least giving the balls as held items, but then you can't give some Pokemon forme-changing items at the same time haha). If anything I wouldn't mind a feature where you can "assign" a specific ball to a Pokemon and just have it look pretty.
