Patricia,
You cannot create new placeholders. You are limited to a 'title' and a
'bullet list' placeholder only.
You can insert a "title master" to create another slide master....but you
are still limited to two placeholders.
If you need extra text on each slide...e.g. a sub-title. Then it's probably
easier to create several slides. Then duplicate the slide before editing it.
