I changed the Footer Template as shown below. This makes a separate First Slide with Song Title, Songbook, and CCLI Number. Then the Footer has the Song Title, Authors, Copyright, and CCLI License. The Add First slide needs to be set to "same as Footer".
There is no ccli_number_label so I had to use English Text.
This might be useful sample for others.
## First Slide START
%if first_slide:
${title}<br/>
%if songbook_entries:
<br/>
<%
entries = ",
".join(songbook_entries)
%>
${entries}<br/>
%endif
%if ccli_number:
{sb}<br/> CCLI Number
${ccli_number}<br/>{/sb}
%endif
<% return STOP_RENDERING %>
%endif
## First Slide END
## Footer START
