MATLAB: How to group same buses together over a MUX

MATLABsimulink

This is my Bus file :
    %my_bus.m
    cellarray = { ...
    { ...
        'Status_Queue', ...   % Bus Name
        'status_queue.h', ...         % Header File
        'Queued Data', ...          % Description
        'Imported', {...                % DataScope
          { 'Data_ID',1,'uint32',-1,'real','Sample','Fixed'} ; ...
          { 'Copy_ID',1,'uint8',-1,'real','Sample','Fixed'} ; ...
          { 'Data_X',1,'uint32',-1,'real','Sample','Fixed'} ; ...
          { 'Data_Y',1,'uint32',-1,'real','Sample','Fixed'} ; ...
                    } ...
    }  
    { ...
        'Bus_Status_Queue', ...         % Bus Name
        'status_queue.h', ...           % Header File
        'Queued Data', ...            % Description
        'Imported', ...                   % DataScope
        {...
            {'Count', 1, 'uint8', -1, 'real', 'Sample', 'Fixed', [], [], sprintf(''), sprintf('Valid Messages.')}; ...
            {'Data',5,'Bus: Status_Queue',-1,'real','Sample','Fixed'}; ...
        } ...
    }
    };
    Simulink.Bus.cellToObject(cellarray);
    evalin('base','Status_unpackPtr = Simulink.Signal;');
    evalin('base','Status_unpackPtr.RTWInfo.StorageClass = ''ImportedExternPointer'';');
The problem is, when I'm using MUX to group 5 different Status_Queue (which is a bus) for element 'Data' in Bus_Status_Queue, simulink throws an error stating it cannot group such signals. What is best way to group 5 Status_Queue and pass it to 'Data', using simulink blocks (not api/m-scripting) ?
Also will it be possible to resolve bus names to 5 different xyz_unpackPtr and then group them together ?
Any suggestion/help would be greatly appreciated. Thanks
