How do I add certain Fields to a View (not all fields are showing in Add list)? I'm creating a view where I'd like to output a custom field. I am basing this off an already existing view, which already uses the said custom field.

However, when I hit the 'Add' button in the View's Fields section I do not see the same Fields as the already-built view.

Is there some way to associate the View with a certain group of Fields so that I can add them?

Yes, this is done by adding a relationship.

For example, if you create a content view and add a relationship of Content: Author, you will now be able to add user fields, such as User: Picture or User: E-mail to name a few.

Therefore, look if the already built in view is using a relationship. (It's under Advanced, located on the far right of the View's settings).
