Automatic sync of hieararchical pin name/direction

Description

Editing name/direction of hieararchical pin on sheet symbol should automatically edit hierarchical pin on the sheet and vice versa.

You have pin named "In" defined as input. If I rename this pin to "In2" it should be renamed on all sheets and on all sheet symbols it is related to.
