There's a script for the editor in scripts/sdk.cs which you can activate by going to "Extensions->Configure" in the GUI then restart the editor. The editor will then work with the SDK way of doing worldmaps, which is encounter tables. Problem is that I wrote that script a long time ago so I have no idea if it's still compatible with the revision.
Also you'd need to write a loader script on the angelscript side to properly load the saved data.
