delegate access to unmonitored device list

Currently, it is impossible to grant access to see unmonitored devices in LM without granting full admin access.  In shared portals, it is just one more of the monolithic elements (like alert rules and escalation chains) we can't share, but even in a dedicated portal it is hard to justify full admin for this function.  Please add that to the Settings section in the Role permissions.  In the meantime, we can use scripts to extract and report on those, but folks prefer to use mainly the UI if possible.

Thanks,
Mark
