When creating a help desk role for say 'group management' which only includes the 'modify single group' property, is it possible to further limit what can be modified for the group, for example 'manager can update members list' only?

It appears this feature is available for roles with 'create' properties but not for modify.

What we are trying to achieve is limiting our users modify access for groups to only be able to modify:

-manager

-manager can update memberslist

...with everything else locked such as changing the group name, email, description etc.

Any thoughts?
