Change Authorization Dialog shown by AuthorizationCreate()

Looking through Apples BetterAuthorizationSample and further Derivatives( http://www.stevestreeting.com/2011/11/25/escalating-privileges-on-mac-os-x-securely-and-without-using-deprecated-methods/ ) I am trying to make a small change to the application and gain better understanding of the whole Security & ServiceManagement framework.. Therefore I proceeded to add an a button which removes the installed Job through the inverse of SMJobBless - SMJobRemove(). Straightforward however the AuthorizationCreate() call displays a dialog that states and requests permission to install a helper and not remove it.

That's the dialog I get (by using kSMRightModifySystemDaemons). As you can see it says that my app tries to add a new helper tool. Which will confuse my users because the app actually tries to remove the installed helper tool.

I'm seeking to find knowledge on how this dialog is changed to reflect my actual action (Job Removal), There are also several other apps which seem to completely customize the dialog - showing their own Custom Label and Buttons..

BOOL doRemoveSystemTool(NSString* label, NSError** error)
{
BOOL result = NO;

AuthorizationItem authItem      = { kSMRightModifySystemDaemons, 0, NULL, 0 };
AuthorizationRights authRights  = { 1, &authItem };
AuthorizationFlags flags        =   kAuthorizationFlagDefaults              |
kAuthorizationFlagInteractionAllowed    |
kAuthorizationFlagPreAuthorize          |
kAuthorizationFlagExtendRights;

AuthorizationRef authRef = NULL;
//Obtain authorization
OSStatus status = AuthorizationCreate(&authRights, kAuthorizationEmptyEnvironment, flags, &authRef);
if (status != errAuthorizationSuccess)
{
    NSLog(@"Failed to
