updating web styles

[SLouq]

Hi all,

I have a group of styles which I shared as a custom Utility.style to my ArcGIS Online account. I want to update this group with more utility styles and was wondering if there was a way to add to the existing Utility.style  without overwriting the whole style

You will be using ArcGIS Pro to share a new web style that will overwrite the existing one. There currently isn't an update workflow for a web style.
