Importing Issues

Still fairly new to Lingq. How can I organize or import many different items into lessons by teacher or subject? How do I organize and group lessons or ebooks after they are uploaded? Any way to combine lessons so they are organized by topics after the fact? I am still finding it difficult to start a new thread in a forum. I don’t see the plus sign to create a new topic anywhere. If I upload a lesson that has both English and Indonesian and then go back and delete some of the English using edit is there a way to recombine the sections of a lesson to put them into a better sequence such as chapters or groups of paragraphs rather than merely word count?
