What if one can develop on function of IV using $f(x_1,x_2,x_3,x_4) =b_1x_1+b_2x_2+b_3x_2+b_4x_4$ obtained from previous multiple regression model from SPSS. This can be computer using data → transformation. I believe the function obtain will be the weighted result of X which is one IV then you can use Hayes processor to obtain moderate mediation of 1IV,1 mediator and 1 moderator. I may not have supporting evidence but open to discussion.
