Easy way for instance positions

Hi everybody. I'm working on a menu system. I have menu sprite instances. Depending on choice, sub-menu size and positions changes (by choosing different frames). In some menu options i have to reset them to their beginning positions. I tried to put them back by picking each instance one by one and giving specific position. But it's very ineffective. Without resetting layout is there a easy way for putting back them to old positions?

easiest way (may not be the most effective) is creating event-groups for the different layouts and setting these groups to active or not active depending on conditions met.
