You can listen to menuselect with listener. This way you will know (at least for menus) when client pressed next or previous. Here is example code for cs:s. If you need it for cs:go, change +- in listener from 7 to 6 and arg == (8 and 9) to (7 and 8). If you write "sm_open_menu" in console you will see menu. You can move forward and back. Then you can write "sm_interrupt_menu" to interrupt this menu. If you type "sm_open_menu" again you will see interrupted menu on page you previously was. But if you close this menu via exit, typing this command again will always start from 1 page (so it restore page only on menu interrupts).
Hope this is what you wanted.
