The current roles with filter, only allows for filtering of the object itself - which the permissions is granted.

E.G Parameters cannot be filtered - so either you can edit parameters or you can't (site wide)

I'm looking for a way to limit editing parameters to a set of hostgroup / hosts only - but this doesn't seem to be possible. I can set up regular host permissions, like create/destroy/power on etc. on spesific hosts, but not edit parameters for the same host (only)
