Separating the subdwarf populations may shed light on their formation history and give unique insights into the atmospheric processes that are thought to be responsible for their abundance diversity. Such a task requires complex and time consuming spectral analyses, which we started to tailor to our objectives a year ago. Here we report the updates that have been made over the past year and will be the standard method in SD1000. ; Comment: 8 pages and 3 figures; to be published in the proceedings of the Sixth Meeting on Hot Subdwarf Stars and Related Objects
