Describe the Suggestion

Not sure if this is a bug or just a suggestion, so I'll put it in the more positive light.
When a deployer uses a fishing rod, it should create the fishing bobber entity both to add a visual note to show that the fishing line is cast, and so it can be manipulated like the bobber that comes forth when a player uses a fishing rod.

Namely, I want to be able make the below image work as an auto-fisher, instead of relying on the random chance or pulling in the fishing line when there happens to be a fish.

Screenshots and Videos

Additional Context

This video shows how a bobber can be captured by a boat and how that interacts with whatever is on the hook.
