During trying to assist in copying content over from a Powerpoint format into a course as is needed due to another idea which I submitted Improve PowerPoint Import , it was found that sub-items in an unordered (bulleted) and ordered (numbered) list does not seem to be possible in the current course interface. Upon searching for it in ideas, I found an archived idea Sub-bulleting/Sub-nesting of Lists Limitations , but it looks like there is nothing else out there currently.
It looks like I am going to need to get creative. (Please note that I am a Web Developer/Application Administrator and not an Instructional Designer.) This seems like something that should be basic, but is missing. The first training for this area is already 103 slides, but I guess it will need to get longer.
