User only should see one application with its jobchain- and jobdefinitions

Hello,

I want to give one user the rights to see only one specific application (XYZ) with all its jobchain- and job-definitions.

The user has a custom-role with scheduler user in it and no priviliges.

The application-security for XYZ I set to "view" for the role the user has. But the User only can see the application, not the definitions in it. How I have to create the user that he can see also the jobchain- and jobdefinitions?

If I set the security for single jobdefinitons for this user to "view" then he can see this jobdefinitions. But I have mor than hundred jobdefinitions and don't want to do this for every jobdefinition.

Regards
