[4.1.5] Pushable block?

[FormulaFanboy]

Hello all. I am hoping someone may be able to help me.

I am creating a game in the adventure module.
I would like to have a "box" tile that the player can push by walking into it. Additionally, tiles in this game are 32x32, so it should move 2 tiles in whatever direction the player is facing. Would this be possible, and of so, how to do it?

Thanks in advance.
