In my game, I would like to add a lot of items, like a couple of hundreds of them. The only way I can find to add items is manually, and by copying existing ones and editing them. I noticed that on several of the other configurations you can instead upload a json. Is there any way of uploading items in bulk. It would save me a lot of time if I can manage the data in a text editor (using find-replace and such to easily set up stuff according to naming conventions) and upload it instead of in creating everything in the browser.
