Describe the bug

use-form supports form.reset() but nothing like form.reset('name').
This is crucial when wanting to reset only "name" to its original value, not the whole form.

Some context:

• We initialise like this:

  const form = useForm<Inputs>({
    initialValues: {
      image: workspace?.image || '',
      name: workspace?.name || DEFAULT_NAME,
    },
    validate: {
      name: (value: string) => (validateText(value, 2, 30) ? null : 'Name must be between 2 and 30 characters'),
    },
  })

• UI:
  

Cancel button should reset only "image" to its initial value: workspace?.image || DEFAULT_NAME
There's no such functionality. Please implement it.

If possible, include a link to a codesandbox with a minimal reproduction

You can do that by calling form.setFieldValue('name', workspace?.image || DEFAULT_NAME).

@rtivital form.reset() resets to the latest value before it became dirty. It may not be the same as workspace?.image || DEFAULT_NAME.

So form.reset("name") is completely different, that's why I posted.

[atumas-bananamilk]

So 2 ways:

• either let us fetch initialValues
• or let us reset 1 value form.reset("name") (preferred option)

Really need it, please.

I've seen the request and added it to the backlog, it might be added in one of the next minor releases. Currently, I'm busy with 8.0 release preparation.
