Assign specific permissions to JasperReports Server's Users

Hello everyone !

I would like to know if it' is possible to assign specific permissions to JasperReports's users (not only read, read+write, ...), like the permission to publish content or to manage datasources for example, is it possible in JasperReports server ?

Thank you in advance for your help !

Examples of permissions : 

* Administer Security

* Read Content

* Publish Content

* Manage Data Sources

* Schedule Content

* ...
