Theme: Symbol, component in schematic
Names of connectors should have the prefix X, not J. How to set this?
In schematic view go to the component browser. Choose: "Extra/Edit component types and groups..." .
(Image 1: Edit Component types)
For every component type that you like to change, you need to set the user prefix to the desired character. Press the [Save] button each time.
All components imported to the project now show the desired prefix, in this case all Board connectors will show prefix X.
