Can I use the console to prepare monthly data for a segment?

I’m using segments for large parts of a site (one segment for each faculty of a university). While monthly reports have a good performance for the whole site - thanks to archiving - monthly reports for segments always run into a timeout.

Is it possible somehow to also pre-process the monthly statistics for segments?

Yes, you can set any segment as “Pre-processed” when editing a segment. Look into the top right corner of “Segment Editor” panel. Doc: Segmentation - Compare segments of visitors - Analytics Platform - Matomo
