Add shape to Title or Footer (in slide master)

[Amelia]

Hi,

Is it possible to add shapes or another text box as a 'real' title element?

For example: my title consist of only a text box (the one that appears when I click on "Title" checkbox in the Slide Master ribbon). I would like to add a line underneath that title, and another text box as a subheadline.

I know how to do this in the actual Slide Master. But I would like to turn them on and off individually in the different Layouts (via the "Title" checkbox).

Thank you for your help!
