ability to transform a prop into desired state structure?

A callback to process props/param inputs into the a Surface.LiveComponent's state would be helpful.

The mount/1 callback doesn't have access to the props yet. The render/1 function doesn't feel like the right place.

Here's an example. Let me know if you see a better way to solve this.

<MyOptions item={{ item }} />

An item may look like this:

%{
  name: "Thing",
  options: [{"display text", "value"}]
}

I want to edit the "options" value. I need to transform it into a structure I can work with more easily. Additionally, it would be helpful if it had an ID for handling edits and deletes. The ID can be generated using Ecto.UUID.generate(). The desired structure might look like this...

%{
  id: "c9215b61-e5af-410a-a84e-fa4195931eb6",
  display: "display text",
  value: "value"
}

There currently doesn't appear to be a good place to perform this transformation from a prop value into the state I want to manage internally.

Nevermind. The update/2 callback is there and works well for this. It just isn't in the docs (website) that I was looking at. 👍
