Does baker implementation currently include a way to tell node what block it wants to bake on?
Edit: I want to know if what does baker do after it finds out it has a baking slot? What I know is that It asks node to send the a block which node has been preparing since last block it received, signs it and ask node to inject it. I am curious whether baker can ask node to extend any head of their choosing, or it is completely upto node to decide which head to extend using this new block.
