Or use "reltoolbox" plugin, where there is a notion of current                                                   
relation, and while you got your relation selected as current,                                                   
adding or removing objects to it is clicking "+" or "-" icon on                                                  
the sidebar, having object selected. For multipolygons it will also                                              
set "outer" or "inner" role automatically.
