Can the auto fill be smart enough to see what we play, and not what what we are given?

i normally play jungle and secondary support, since i have only ever got autofilled into non-support, once its not much of a big deal to me, but i think for others it might be.

the thing is this... i was given jungle... (my primary role). but the person who got support wanted jungle.. and being the nice person i am... i gave them it and i took support.

but after we won the game... i get have "auto-fill enabled" even though last game i ACTUALLY supported and not jugnle.. even though i was SELECTED as jungle.

since the mastery system already knows what role we are playing. why cant the auto fill feature realize that went support? and not auto fill me?
