Description:
I would love to have the ability to add custom AutoLayout fields to my master slides.
So for example there would be the possibility to have a field to add source references on each slide at always the same specific place and formatting but with different content. If one chose to alter the placement afterwords it would be possible to just move the AutoLayout textbox in the master slide.

Steps to Reproduce:
Create a presentation and add a field for sources on each slide.
Now I want to have the source field somewhere else on the slide.

Actual Results:
I have to move the source field on every slide.

Expected Results:
I have an AutoLayout TextBox for sources in my master slide.
Now I can move that and all source fields on all slides move accordingly.


Reproducible: Always
