Depth of Field, DOF in gameplay mode???

I am trying to add depth of field/DOF to my map, from the players pov, but unlike full blown UE, there does not seem to be an option for this. Is this feature supported outside of the cameras in sequencer, like we have in full blown UE?

Essentially, I am trying to make a level feel macro, so shallow dof, like this example from the full UE where its easy to activate. There seems to be no option in the post process for DOF control or elsewhere. Thanks for any info on this feature in gameplay mode (again, not sequencer)
