I'm using the SMS service now, and it works great, but.... Using multiple users that have privilege over certain customergroups in LMS, I notice that indeed only the selected customergroup for that user is showing in the section "Messages". That works, however that user can also select "- all networks -" from that customergroups list and that shouldn't happen I think.

I want the user that I created in LMS to have ONLY privilege over the customergroups I selected for that user. Is that possible?

Does anyone have experience with the customergroups privileges for users (admins) in LMS? I don't know how to fix this. Thanks.
