Help with context of StateView model

I am implementing a party creation wizard, loading the data, and opening the form with:

class MyWizard(Wizard):
    "My Wizard"
    __name__ = 'xxx'

    start = StateTransition()
    create_party = StateView('party.party', 'party.party_view_form', [
            Button("Cancel", 'end', 'tryton-cancel'),

    def value_create_party(self, fields):
        pass

The problem is that I want a specific company to appear in the party context. (For Multivalue)
Is this possible to do? Or is it a missing feature?

Doing it this way works, but I want to do it individually.

class PartiesWizard(StateView):
    "Parties Wizard"
    __name__ = 'party.parties_wizard'

    company = fields.Many2One('company.company', ...)
    parties = fields.One2Many('party.party', None, "Parties",
        context={
            'company': Eval('company', None),
            },
        depends={'company'})


class MyWizard(Wizard):
    "My Wizard"
    __name__ = 'xxx'

    start = StateTransition()
    create_parties = StateView('party.parties_wizard', 'xxxxxxx', [
            Button("Cancel", 'end', 'tryton-cancel'),

    def value_create_parties(self, fields):
        pass
