I've added 1/2 the headwind component as a rule of thumb, but you have to be cautious with having a higher airspeed prior to the landing as it will change the profile and could make the landing more difficult.
Probably even more important is to develop the judgement to pick a landing spot that is possible using the standard autorotation speeds. Maintaining one technique, but considering wind in selecting a landing spot should be easier than learning many different autorotation profiles.
