Multiple save files in New Horizons with Yuzu

Hi! I managed to get ACNH working and am having a blast, but i was curious if i could have multiple save files/islands per pc. I found some old posts talkig about creating separate files of the games and using them as separate files but there was never a clear conclusion if it worked or not.

Im kinda chicken to poke in the thing on my own so i dont break anything, so im asking yall, more knowledgable folk in this matter, would this work, or is there a secret method i dont know about? Thank you :))
