Just use the magenta ILS course line on the compass segment at the bottom of the PFD. Assuming a 30-40 degree intercept, roll to 20 degrees of bank (+/- a bit based on wind etc)when the localiser comes alive, and aim to line the green track diamond up with the ILS course as the deviation comes to zero.
That sounds more complicated than it is, but I find this much easier than chasing the track on the bird.
