PS 1.7.1.2 - Fields mandatory for user group

[Fabrizio r]

Hi, I would like to make the VAT field mandatory only for the "company" user group, and the DNI field (Identification number) mandatory only for the "private" user group (in Italy it is necessary). It's fine both in the registration form and in the checkout form.
Is it possible to do this without paid forms?

Thank you
