We've been playing with manager approval in seminars and have found it works exactly as we need, up to the last user within the management chain.

Should this user wish to also sign-up to the seminar, they are unable to as they do not report to anyone within the system.
I've hunted through the permission capabilities hoping to find a setting that enables a user to override this requirement, but have come up empty.

Is there a way to flag a user/role as being allowed to bypass this requirement or self approve without giving them god like powers to the seminar?
