Hi:
When you use any of the #byval or #byline features, the text is the same and the only piece of the title that changes is the #byval -- in this case only the year changes.
If you create your output with BY groups and save it the output in an ODS DOCUMENT store, you can manipulate the output and/or put a completely different title or footnote for every BY group using PROC DOCUMENT statements.
There is an example of doing something similar on page 21 of this paper:

You can see that the OBBNOTE statement set the title for Canada to 'Something' and the title for Germany to 'Something Else'. The OBBNOTE is a "before" note and the OBANOTE statement would be set for an "after" note.
