Assign/get custom key value for useFieldArray

[donysukardi]

Is your feature request related to a problem? Please describe.
I'm using useFieldArray with controlled <Accordion> component from ant-design. Newly added entry would have to be expanded by default. In order to do that, I need to have the key value of the new entry to be added to Accordion state.

Describe the solution you'd like

• Assign custom key value, or
• Get assigned key value returned from append, prepend, etc.

Describe alternatives you've considered

• I've managed to get it work by assigning custom key value with append({ uuid: 'xxx' }). However, I'm getting warning: useFieldArray fieldValues contain the keyName uuid which is reserved for use by useFieldArray.

Additional context
N.A.

U should use ur own key and stored in a hidden input, hook form id is purely made for react render.

[donysukardi]

Understood. Though I think it'll be useful and reduce workaround if we could have something like

const id = append({})
