You can use a Django QueryDict object:

from django.http import QueryDict

# from scratch
qdict = QueryDict('',mutable=True)

# starting with our existing query params to pass along
qdict = request.GET.copy()

# put in new values via regular dict
qdict.update({'foo':'bar'})

# put it together
full_url = reversed_url + '?' + qdict.urlencode()

And of course you could write a convenience method for it similar to the previous answer.
