Some user role question.

Some user role question.

Hi,

I have some problem in user role.  Here is problem that don't know how to do it.

1. I have read the access restrictions role table but not sure that is can I do some customs ACL.

Example:

- Can I limit which user who they can read which IP info in network monitor?
- Can I limit which user who they can read which zone where I have pre-defined?

Additional

2. Is that have any addon it can included the netflows featous together?

Thanks in advance.
