possible to make isort behave like a from_last was done?

[mshafer-NI]

I'm trying to configure isort to match the smarkets config (example: https://github.com/PyCQA/flake8-import-order/blob/master/tests/test_cases/complete_smarkets.py)

I appear to need force_sort_within_sections = true, but then an explicit from_last = true (instead of the from_first = false option...

Any ideas on how to do this? is it possible with current isort versions?
