Powerpoint: Manually set Slide Name

Context: A PowerPoint slide in C# has a property Slide.Name (usually contains an arbitrary string value). In my C# application I would like to use this property to identify slides (the slide order is to unreliable).

Question: How can I manually set the Slide.Name property in the PowerPoint Application?

My problem is very like to the: “How to name an object within a PowerPoint slide?” but just on the slide level.

Any help would be appreciated.
