UddeIM and usergroups/access levels

I installed Community Builder and UddeIM in my Joomla project and everything works fine but when a user create a new UddeIm message there are an option called User List where all the users are listed so all of them can be selected. I don't want this user to be able to send messages to users who are in a different usergroup/access level in Joomla/CB.

Is there any way to configurate UddeIm so a user only can send messages to other users that are in the same usergroup/access level on Joomla/Community Builder?

Thanks

I am sorry. UddeIM does not support access levels. It is only possible to block certain groups.

I ended up hiding the "all users" option so I still can send one message to different users if the are in My connections.

Thanks
