Yes, you need a separate module with the list and its properties (like LI).
This would be double work, since it corresponds to Anaplan practices and in most cases you would not need to duplicate these values in the properties (you could do a direct formula in a pinch).
Overall, you will get (if you use module):
1. Ability to filter properties 2. Possibility to store some of the properties on subsets 3. Ability to output on UX 4. Ability to flexibly access properties via DCA
At one of the events Anaplan said that in the plans of UX development there is a possibility of direct output of the list and its properties. But I wouldn't use this unless there's a good reason (e.g. you only need this data to be updated through ALM).
