Are there ways to make a Pokémon evolve prematurely?

I know that in the canon of both the original games and the anime, it is possible to force Pokémon to evolve before they reach the right level (Such as the Gyarados at the Lake of Rage). Is it possible in PTU as well to make a Pokémon Evolve without providing the conditions that are normally needed? Such as the right level, evolution stone, or others?
