Changing state of menu position to visited when slide was visited

Hi,

I have a little issue, and to be true, I don't think it will be possible to do. But maybe you have some idea ;)

I'm building big presentation (around 200 slides), it will have index, main menu and chapter seperators with submenu to slides. Almost each slide will be connected to position in those menus. My question is, is there any fast way to change positions in menu to visited, when user VISISTS slide, not CLICK from the menu?

For example, user from chapter separator chooses slide 120, then clicks through 130. When he backs to separator or index, only 120 is marked as visited, 121-130 are still not visited. And in my dream scenario, all positions 120-130 are marked visited. 

Only solution I can think about, is variable true/false for each slide, and then triger them to the positions in menus. But you can imagine how many work it will be, so that's not solution I'm looking for. Any counting variable isn't a go, user might go to diffrent chapter at the start.

Thanks for any help,

Cheers
