Thanks for this tip! Was curious to test: import a quad object - start tool - quadrantalize - increase subd level. Sometimes it works nice, sometimes it totally makes a mess of the materials / material channels. Creasing seems to work.
Tried making a BP so by hitting a key you could increase the subd level but it didn’t work. Didn’t find a way to convert a static mesh to the right type of object.
Hoping this will be enabled, and documented, in a new UE version soon!
