Show "evolves into this monster"

[Terrorforge]

The page for a given monster shows which monsters it evolves into, which is great. But I often find myself wanting to follow the evolution path in reverse, e.g. seeing which other monsters evolve into, say, a zombie hulk. It would be nice if this information was also present, say as an "Upgrades From" section above the "Upgrades Into" under "Behavior".
