If you've already got your season's fixtures in a spreadsheet from your league or wherever you've been tracking them, you can upload it directly rather than typing each one in.
Upload your file and map its columns to Dugout's fixture fields. You'll get a preview showing exactly what will be created, with any row-level problems (a missing date, an unrecognised format) flagged clearly before anything is saved, so you can go back and fix the source file rather than cleaning up after a bad import.
This is a one-off bulk load. For a team whose results and table are already published on FA Full-Time, connecting that instead keeps things updated automatically going forward rather than needing a fresh import each time.
