As the expAll menu property is now going through stdWrap¹, it would make sense to have the current sub menu uid at hand. I propose to store it in a register named SUB_MENU_uid.

This will allow me to expand only some elements.

    expAll = 0
    expAll.override = 1
    expAll.override.if.isInList.data = register:SUB_MENU_uid
    expAll.override.if.value = {$PID_LIST_EXPALL}

where PID_LIST_EXPALL is a list of page ids I would like to expand
