Target Man(Attack) is still a support player? Or not?

[Mr Phalanx]

How much running behind does a target man(attack) do? The back-to-goal play is nice but does he want to bomb forward into the box immediately after laying it off or still make himself available for combinations. 

Maybe a poacher with "plays with back to goal" trait and the option to hold up the ball might do the job. The poacher already occupies CBs, he wants to run in behind, and doesn't run with the ball like the other forwards.  Perfect base behavior for what I want. 

I really wish traits were clickable options, or roles were more customizable.
