4High with locked differentials?

I have the 2015 G550 where you have to be in 4Low to lock the diffs. Are there any hacks out there to get around this ? I spend the overwhelming majority of my time in 4High and would like the option of locking the center and rear diffs. I have zero interest in rock crawling or taking the G into deep mud holes but could use the extra traction in the snow, sand, gravel or muddy forest roads that we have here in Pa without having to be in 4Low crawling along at 10mph.

I understand they did away with this setup in 2016 so I can’t be the only one bothered by this.
