Need help adding specific Gmail inbox shortcuts to homescreen, tap & hold method only lists 5 of my 20 gmails

I know I tap and hold gmail and it pops up with the email address and then i drag that to my home screen. GOT IT…. the problem is i have like 20 different gmails. when I long press it only gives me 5 of them. I wanted to create a folder on my homescreen that has shortcuts to the inbox of various emails. Are there any other ways of creating these shortcuts???
