In order to quickly modify checklists that have been used throughout our company, we currently import a checklist from our account into our respective project. From there, find the checklist, export it to a cvs file and then copy and paste into the sample form for importing after we have made our edits / additions / subtractions. Manipulating an existing checklist is far more quicker than within the system, so my suggestion is that when we export a checklist, that the export file is actually in the same form as the import file, so that there is no copy and paste required.
