Question about atlas map variety in 0.3 for Standard characters

Could someone please tell if there is a way to regenerate atlas layout on old character in Standard? I remember GGG stating in some old patch notes about "atlas has too few map layouts, we're increasing it". Does it apply to existing characters? Because I still see only Augury, Crypt, 2 swamps, and a meadow maps here.

Won't be the first time Standard left totally neglected out of base QoL features, but maybe I missed something here, what are your map layouts on temp league?
