saving the animation frame of multiple instances of an object to an ini file

I have 16 objects titled “Active 1” that each have 4 frames in there animation. When a user clicks “Active 1”, its animation will jump to a random frame. When the user ends the application, I want the ini file to save for all instances of “Active 1” and load when the application is restarted. I can do this when there is only “Active 1” but I’m not sure how to do it for 16 of them. Any help would be appreciated!
