Hello, I'm trying to set up some of my projects in FogBugz to force-assign to a certain user upon creating a case. That part works fine:

Looking at the verbiage of the workflow plugin (as highlighted) I would expect users should not be able to change the assignee once it's active, aka right after it's been created. However, it would appear this is not the case:

And

Though, it does appear to work when I try to change the category ("Feature" is setup the same as "Bug" in the first image):

I would think this is not the expected behavior, or maybe I'm misunderstanding the intent of these controls? My end goal is to essentially force "normal users" to assign new cases to either my boss or a virtual "unassigned" user. From there I would like no one but my boss to be able to assign these newly created cases to one of his employees. This works great when I have community members submitting cases, as they don't get to pick the assignee, but I'd like this to happen for certain "normal users" as well. Perhaps there's a plugin I'm not aware of that can help me achieve this?
