powerpoint software training - Slide masters

Hi Catherine

Thank you for your question.

The answer is yes, you can.

Using the slide master toolbar, you can insert a new slide master or insert a new title master.

If you wish to have access to all your master slides so you can change which one you apply to your presentation, then it is important to preserve each master slide, which there is also a button on the master slide toolbar for.

I hope this helps.
