Great Weapon Master in Beyond 20

Is there a way to automatically role Great Weapon Master when you click on an attack role? I know there is a button that turns it on for one roll only but I used to have it show up in the Beyond 20 box and could turn it on there. I'm wondering if there is a setting I missed or changed. Basil the Wrecker my barbarian would appreciate any help. He's not that bright

D&D Beyond does not provide support for Beyond20, which is a third party extension. You would be best off contacting the developer
