Using UA subclasses in DnD Beyond character creator

Hey all,

I haven’t been able to find any super clear answers after a few searches online and I’m trying to figure out if I can build characters using the new UA subclasses on DnD beyond to theory craft builds, or if I just have to make the character sheets manually.

I saw something about being able to change a setting to allow playtest content but can’t find such a feature on the site or app.

Thanks for any answers!
