Can I collect, on behalf of my family, our Visas

We are a British Family, residing in Geneva with Permit Cs, travelling to Shanghai. We submitted our passports to the Chinese Embassy in Bern last week for the Visa Applications, as a Family, and i want to know if it is ok to collect our passports with visas this Wednesday on my own, or do we all, as a family, have to go back to Bern??
