Question : How update a line

Is there a way to update the value of a line ?

Now I'm using :

```
let guestCopy = fields.value[index];
guestCopy.bookingOwner = true;

fields.remove(index);
fields.insert(index, guestCopy);
```

But it's a little bit dirty

Review the fields.value, fields.remove, and fields.insert usage shown in the report and check the library's documented array-field API. Confirm whether an in-place line update is supported; done means documenting the supported approach or identifying the missing API, with a focused test if implementation is needed.
