To further my thought is that you are confusing "written citation" as prescribed by Chicago, Evidence and others with data storage and collection.
For example: You pick up a paper with obituaries in it.
The first thing you do is record the data about the newspaper which includes the publisher information and the date of the publication. This is entered on the source screen in FTM. Select new source (not source-citation) and find the newspaper/newsletter template. You will see that the date along with the volume and other publication information is captured.
Second you look for the obit you are capturing and "cite" the information about that obit for example the page number. If you found 20 obits on 10 different pages all you would do is enter 10 different source citations with 10 different pages. NOTE: some software does not share source_citations so you must enter 20 one for each obit used. No need to enter date or any other publisher information again.
