How do I authorize a user group to edit a single category

I was hoping that categories in jEvents would work like article categories with respect to authorization. On my site I have several category blogs. I have a user group that is authorized to create, edit, and publish articles for each category. I do not authorize those user groups to global article authority in the site configuration articles permission area because that grants authority to all articles, and that is not what I want. This works nicely. I tried to do the same with jEvents categories. I have a user group that is authorized to create, edit, and publish events to each jEvents category. I did not authorize those user groups in the jEvents global configuration permissions because that grants authority to all jEvents categories which is not what I want. Unfortunately, unless I grant global jEvents authority to the user group, the user is not allowed to create, edit, or publish events in any category, even if the category grants specific permission.

So, how do I grant authority to a single user group to create, edit, and publish events to a single jEvents category when there are multiple jEvents categories defined.
