How do you import data?

Is there a way to bulk import foods? I'd like to import some foods that are not included, like things you would use as a raw feeder: brewer's yeast, bone meal, nutritional yeast, meaty bones, etc. There are some spreadsheets out there with these foods, but I don't see a way to bulk import into food wizard. Also, if many of us are taking the time to add the same foods, it would seem like a good idea to have a way to "share" this and so then someone who has already imported or added these foods into this program could then share a file with others. Is this possible?
