What is best way to cover everything with only one-umpire?

I also like to enlist my scorer's help. I tell them before the game that I want them to help watch time plays at the plate for me. I tell them to be aware of runners crossing the plate when I making a tag call at 2nd for the 3rd out. I also let them know that it is my call and that I'll come to them only if I need help, which I've never done. For me it's like using the signal for potential infield fly, just reminds me to be looking for it plus it usually makes the scorer feel more apreciated that the blue wants their help and it never hurts to lift someone up .
