I asked a similar question some time ago and unfortunately
/get_model_filename/ is not enough.
The problem is that the code has /“file = self.sequence + '.xxx'”/ and
/“root_name=self.sequence”/ and /“root_name=sequence”/ sprinkled all
over the place
Indeed, as I said it would require changing the Python code. But since
that is very easy I just did so - will be in the next release.
