new formwizard - how to pass data between forms

Hi all,

i am using the backport of django's new formwizard (https://github.com/
stephrdev/django-formwizard).
and i am looking for the recommended way to pass data between the
different forms/steps.

Basically i am using the formwizard to process a series of forms that
let the user (further) specify filter options from step to step.
For example in the first step you would choose from a list of
countries, the next form would give you the states form these
countries and the final result of the wizard (done()) renders a list
of the major cities in these states.

If i use get_form_kwargs (https://docs.djangoproject.com/en/dev/ref/
contrib/formtools/form-wizard/
#django.contrib.formtools.wizard.views.WizardView.get_form_kwargs) i
can access the data from the previous step via self.request.POST and
pass the selected choices to the form constructor of the next form
where i then filter the choices of the relevant field.

But is it also possible to access the selected data fron step 1 in
step4?
Something like get_all_cleaned_data() but just for the processed
steps?
