PC Question: Get zombie to target specific block

[emantzipator]

I created a recipe and block for crafting a mannequin mine.  I was wondering if anyone knows of a way to set a target priority on a specific block for the zombie AI to attack.  I wanted to create an exploding dummy using meat, nails, gunpowder etc and make it "appear" to be a player to that AI.  Something that you could place and use either to take out a group of zombies or set up to be an early warning system.

Thoughts?

Thoughts? I think that's @%$#in awesome and I wish I could help you but I have no clue if it's doable.

Back when smell was a thing it would have been trivial probably.
