Automatic filling of properties based on value list

Automatic Filling of Properties.pdf (Desktop, Web, Mobile)
This is the document for auto filling but it seems only for object. Not sure about the one I mentioned in the question.

Why would you have 2 separate value lists with basically the same content exact for different names? You can convert the first value list to an object type and then just add the full name as text property. With that in place it should be easy to autofill the full name using one of several methods available.

Alternatively, you could make the second value list a sublist of the first list. You would then have to go in and edit the Department names to create a relation to the department codes. However, this does not make much sense as long as you only have one sublist item for each item on the main list.

With regards to your alternate suggestion using a sublist, am i right to assume that even if the sublist has a one to one relation to each item within it to the main list items the field won't auto-populate and will still need to be selected?
