No matter what, SPOP require's preparation. He needs to kill 6 people and implant multiple Black Receivers into their being. Obito's case was special since he utilized reincarnated Shinobi in Kabuto's control. It's also implied to control a Pein you need a black receiver on yourself. This is proven in the Manga where Nagato is shown channeling his Chakra through the black receivers on his body. The picture can be found on SPOP page. And that for the best effect one must be close and at the highest point possible.

So basically Nagato has to find a location where he can be high up, kill six people and embed them with Black Receivers, and hope that the battle takes place close to his high point. Obito is not a good example because his Peins were extremely different due to being Reanimation and being on his side to begin with. And if prep time is given, then Minato can do a hella lot with prep time such as implanting kunai throughout the battlefield and around it, as well as a dozen other places to teleport to.
