I have a technician working in a remote site supporting users in that site. 

I have created a role (site technician) and set the "Technician allowed to view" setting "all in associated sites."  

For the requests this is working well - the technician can see the requests from their site, but not others.

However, this setting also limits Changes and Problems.  I would like to have it configured so that the technician can see Changes and Problems in all sites.

How do I set the role up to allow this? Is it possible?

Thanks

Sam
