Reference a specific array index in mapFields?

[dpeckham]

Using Vue 3. My data model is like this: a.b[n].c

I have a component which can render a single "c".

I want to do this:

@Component({
  props: ["index"],
  computed: {
    ...mapFields({
      c: "a.b[index].c"    
    }),
  },
})

Is there a way?
