When creating modules for a K-5 environment or even a UDL design of a module it is best practice for a designer to chunk the data into small amounts of data on each "page" of the module.  Also, a UDL design would be to allow students to visually see what items they have completed and which items they still need to complete so the requirement feature in Canvas is AMAZING! However, having to use a drop-down each time we want to add a page to the requirement is very tedious work.  I suggest that this feature becomes a checkbox where you would see all the items in the module at one time and then the designer could put a check next to the pages they want as a requirement.
