Set web layer categories in ArcGIS Pro before sharing

[RobGordon1]

I can't seem to find out how to set an item's category in ArcGIS Pro before it gets shared to ArcGIS Online. I had thought this would be as simple as setting the description or summary but actually this doesn't appear to be an option.

I am assuming that this is because the organisational categories are set on ArcGIS Online but there must be some way of doing this otherwise it can't be automated.

Any help welcome, thanks

Hi @RobGordon1 ! 

At the ArcGIS Pro 3.5 release, you are now able to apply categories during the publishing publishing process in the Sharing pane.
