I told you before:

settings->sets to enable/disable the sets you want (regular expressions can be used in the select sets edit box, and/or the available sets button can be used, too)

Another option is to scan all sets and hide the fully missing sets afterwards by disabling sets->popupmenu->view->show all missing sets (and toggling 'sets' in the main dialog).
