Define to which menü item the "read more" button of a easy blog showcase module links

Hi, can I define to which meny entry the read more button of a easy blog entry displayed in an Showcase module links? I have a blog about an event. The entrys of this blog should link to a menu entry, where all blog entrys of this event are shown (magazine style) (Event 1). Then i have another event (Event 2). All blog entrys of this second event shall be shown at another page (magazine style). How can I manage that all the "read more button" of the showcase module of event 1 are leading to the magazin style page of event 1 and all entrys of showcase module of event 2 are leading to the meny entry with the magazin style about event 2s?
