It comes up as part of the immediate pre-match set-up, after you have committed your team selection, before you give your team-talk. You can't access it on a non-matchday.
i thought the OI can be save with the tactics itself... So when trying with a new team just loaded the tactic which include OI we have set before...I don't think you can save it, but if you hold down the Shift key (might be a different key on PC) you can make multiple selections at once to do it quicker.
yup i aware bout that...but with the preset OI.. we also can just change the striker marking instruction without disrupting other player marking instruction..Preset opposition instructions can sometimes backfire lol, like what if their strikers have huge acceleration? You wouldn't want to tightly mark that
