The reason I don't preserve Original symbology from arcgis pro
is because Original symbology has too much color and shape result in a mess in the point view from public user.
For Original symbology preserved from arcgis pro check out other model number not list here.
Therefore, I removed all color symbology, removed all legend. All project, no matter its type, original funding, they are all present as yellow line or yellow square for point.
In public user's point of view, as long as they see yellow things, it is a funding project, regardless it is a line or point or funding type
