35532	Allow customizing errors processing in BaseModelFormSet.validate_unique()	Christophe Henry	nobody	"`BaseModelFormSet.validate_unique()` [https://github.com/django/django/blob/main/django/forms/models.py#L850-L853 doesn't offer a way to customize errors] for instance to provide a more specific message or add the error message to a specific field.

I propose to fix this problem by adding two `process_unique_error` and `process_date_error` that get the form, fields and values as parameters.

Please check the enclosed patch for proposed solution."	New feature	closed	Forms	5.0	Normal	wontfix		Christophe Henry	Unreviewed	1	0	0	0	0	0
