How to pass previous form data to the constructor of a DynamicForm in FormWizard

I have a FormWizard where I need data from the first form to pass to the constructor of the second form so I can build a dynamic form.

I can get the first form's data via the process_step of the FormWizard.

I create the fields of the second form with a database call of the list of fields.

class ConditionWizardDynamicQuestions(forms.Form):

    def __init__(self, DynamicQuestions=None, *args, **kwargs):
       super(ConditionWizardDynamicQuestions, self).__init__(*args, **kwargs)
       questions = Question.objects.filter(MYDATA = DATA_FROM_1STFORM)
       for q in questions:
            dynField = FieldFactory(q)
            self.fields[q.label] = dynField

How can I pass over the DATA_FROM_1STFORM ?

my resultant code: I abandoned the init of the form, and switched it to the CreateQuestions def. Then used the wizard's get_form override to alter the form after creation.

class ConditionWizard(SessionFormWizard):
    def get_form(self, request, storage, step=None, data=None, files=None):
        form = super(ConditionWizard, self).get_form(request, storage, step, data, files)
        stepIndex = self.get_step_index(request, storage, step)
        if stepIndex == 1:
            form.CreateQuestions(request.session["WizardConditionId"])
        if stepIndex == 3:
            form.fields['hiddenConditionId'].initial = request.session["WizardConditionId"]
            form.fields['medicationName'].queryset = Medication.objects.filter(condition = request.session["WizardConditionId"])
        return form
