Filtering Services problem

Hi all.

This is my first time in this forum. I really need your help.

I am trying to filter out host/services depending the user logged in. It seems I can filter hosts using “contacts” or “contactgroups” but i can’t do the same with service.

I would like to show only some hosts and some service for these hosts.

Please tell me it is possible !!!

Thanks a lot for your support
