'MySQL workbench EER diagram, map multiple columns to another column

I'm trying to create an EER diagram like this with MySQL workbench. Is there a way to map two columns (C,D) in Table2 to one column (G) in Table 3?

I also want to make it interactive, so that I can highlight any column of choice and all the edges connected with it. Is this possible in MySQL workbench?

Thanks a lot!
