Rice made in a rice cooker

I’m trying to make 3-4 cups of jasmine rice in my rice cooker on a weekly basis but can’t seem to get a good balance of water for the “perfect” batch. I know I’m using the correct recommended amount but it’s still coming out less than ideal. Anyone have any tips for using a rice cooker? Add anything to the bowl besides the rice and water? Store it a certain way for best next-day-heat-up?
