Feature Request: Embedded lists.

[MattCatellier]

A feature to enable the use of an existing list in another list. Ideally a list would be imported as a category and the category would then be populated with the contents of that list and be calculated at the top with the rest of the items in the parent list. A great example would be a first aid kit. One could have a detailed Lighterpack with each item of their first aid kit. With the new feature they would be able to take that list and drag and drop (or insert) the list into a parent list effectively functioning as a category.
