Add items to listbox using push button and drop down menu

I am creating a GUI using GUIDE in MATLAB2015. I have a drop down menu which the user selects a message to view, after that they click the Add push button to add the message name to a list box and display the data it contains in a table.
My problem is, if I want to add more than one message, instead of adding that message, it overwrites the previous one. Below is my current code:
addData = getappdata(handles.msgSel_menu, 'Data');
boxMsg = get(handles.msgSel_menu,'String');
boxMsgVal = get(handles.msgSel_menu,'Value');
set(handles.activeDataBox,'String',boxMsg{boxMsgVal});
set(handles.data_table, 'Data', addData);
Apologies if this has been done multiple times before, but as I'm relatively new to MATLAB I could do with a little explanation of any code that fixes my issue.

Well, there isn't any magic to creating a cell array - either you replace elements or concatenate with them.
If you want special rules to remove a certain string or not allow duplicates you would just have to program the logic in for that yourself when doing the concatenation.
