Suggestion for Prioritising certain pokemon?

[Makishima]

Anyway a feature could be added that allows you to pick certain pokemon to go for over all the rest. So say you want to farm magikarp and you place your account at a magikarp spawn every time one pops up it will prioritise that pokemon over the rest that have spawn. Also maybe a feature so you can set a max range it walks from you start point for the same purpose
