Just a clarification from page 10 of the English rule book..."When gaining 2 Spades, if you only need one of them to transform a Terrain space into your Home terrain, you may apply the second Spade on another Terrain space. However, you may not ppace a Dwelling on this second space."
So you can transform a second hex with the 2 Spade Special Action, but you'd want to ensure that only you have access to that hex so no one else can steal it before it returns to your turn again.
