I have created a drop-down list using the range shown to the right in the below image. I haven't played much with making lists, so this was just a proof of concept.

Now I would like to refine the way this list is handled. Instead of having the list take up space on the sheet, I would like to convert it into a named value that contains the list, and I can't use macros since the file will be used by people with macros
disabled. As an example, I am thinking about something like the following (Which does not work).

Is it possible to do it this way? If not, then the cleanest option that I can think of is to put the list on a separate sheet and hide the sheet.
Thanks for any help that you can offer.
