How to set layer description for KML conversion

[BenjaminBlackshear]

The KML Conversion documentation (KML conversion—ArcGIS Pro | Documentation)

mentions that "The layer description will be used as the pop-up display content for the folder."

How do I set the layer description? The closest thing I could find to that was the description in the metadata but the description I put there does not carry through to the KMZ

Update to this, ArcMap has a description section when you view a layers properties, but Pro does not for some reason. I was able to set descriptions for my layers in ArcMap, and then import the MXD into pro and the descriptions persist when exporting a KMZ from this. However there is no way to view of edit this description in Pro which is not ideal. ESRI, please provide access to the layer description in Pro that is available in ArcMap.

Still not an option.

In case anybody is wondering, it's in the layer properties, "Display Field".  You can only choose one.

Hi tbrink_DOIT, 

What you are describing is the Category for the individual records in the layer. (For example you can choose display to LAST_Name and you will see a bunch of last names when you expand the data.)

What  is mentioned above, and something I need to figure out, is how do you change the layer description. 

In my case, I copied an old project because I liked the look of the map. I set the data source for each layer to my new data. I use MAP to KMZ to create a kmz. 

When I open my new .kmz file, it shows a hyperlink for each layer and references the name of the old project in the layer description. This is unacceptable because it is misleading. I need the layer description to be blank or reference the current data when I am using the GP tool.
