Omit package names in Sequence diagrams

[MBecker]

For team collaboration purposes and version control we organized our EA model in packages.
Is there, however, a way to omit the package name from the Class information of a Lifeline entity, i.e.  write "ClassName" instead of "PackageName::ClassName", in the diagrams?

We use EA 7.5.

I just found out myself:
Simply deactivate "Show namespace" in the Diagram properties.
