Enable "Send to back" functionality for content add-ins for PowerPoint
In my testing of content add-ins for Office I have found that the "Send to back/Bring to front" z-ordering does not work between the add-in component and other content in the slide. The add-in content is always in front of "native" content in the slide in the z-order. The z-ordering works between add-in content items. This means that you are not able to mix add-in content and native content in the slide - e.g. you can't add a text block over the top of an add-in element.
Thank you for the idea! Although we appreciate your time and effort to give us this feedback, this doesn’t align with the general strategic vision of our products. Can you please provide more information about the scenarios? Thank you!

We are adding custom charts to PowerPoint. Being able to add annotations call-outs and other built in PowerPoint design elements would be a great help. TOday we can't do it due to the above mentioned behaviour,
