[Ylands Ipad Building / Terraforming Nor Editor Able?]

Is it possible to terraform using the ylands apple ipad app? It runs great and don't see why not, but for some reason when I create a sandbox and attempt to make amcave via pick I get error saying terrian mod not allowed or something like that. Wonders if I'm missing something to check box while creating sandbox to allow using the terraforming tools. 

Also wonders if I use the editor on pc and make a multi platform game and publish will that somehow unlock the terraforming?

Also wonders if there's way to unlock the editor on ipad?

Hard to find ipad related help any would be greatly appreciated.
