Many moons ago, the concept of maintaining lists of things, not actions, was discussed. The consensus (although not approved by everyone) was that for such lists, you should use something like OmniOutline or some other list app or even a text file. One example was a shopping list, as I recall. For this, you could have a "shopping" task whose note includes a link to a list file (text file, OO file, whatever).
