This is why you don't have themes yet, its not Lone Wolf at all. Lone wolf needs source data for the downloader to be able to retrieve the data. Since the powers are there they might be able to create a tab and let you input them via the editor though
I am doing a lot of work in the Pathfinder set right now for Dark Sun. I am learning a lot through this process about the editor.
Its not hard to use but you'd have get the Wolf to give you a tab for themes
