Update Web Map's "Show in map Legend" setting from ArcGIS Pro

[zhenghan]

When I prepare web map, I often need to turn off the button below to exclude certain layers from being listed in legend from online map viewers.

While many of the web map settings such as Enable pop-up can be done from ArcGIS Pro, I wonder if it is possible to turn on/off Show in map legend button for my web map from ArcGIS Pro?

Thanks,

I've looked around for this feature also and not been able to find it; not being able to configure this in ArcPro means republishing an otherwise well-configured web service becomes a tedious chore!

Maybe there is already an Idea open for this?
