Hello Nissar,
For the issue with changing the color of Steel Connections please read the following forum thread:
https://forums.autodesk.com/t5/revit-structure-forum/autodesk-steel-connections-for-revit-add-on-que...
In Steel Connections for Revit 2018 you can't create Bolt Schedule, Anchor Schedule, Plate Schedule...etc. This are components that are not separated in the connection geometry. You are not able to select them individually, because of this you are not able to create individual schedules. The only schedule that you can create is a Connection Type schedule.
We are working to change this behavior in a future version.
You can take a peek to the new Steel Connection features in the Revit Preview Release.
