Live Scoring Apps

I posted before about tournament formats for 27 holes, we decided to go with 3 formats:
First 9 - 2 man Scramble
Mid 9 - 2 man Net Best Ball
Final 9 - 2 man Net Combined Stableford

I’d love to do live scoring through 18birdies, golf genius, or one of the other apps, but struggling to figure out how. Any thoughts? Has anyone done something similar before? The apps have all of the formats available, but linking them together into one tournament is the tricky part. Is Google Sheets the best option?
