Post Process (Depth Of Field) To Certain Objects

Hello! As stated id like to apply post process effects to only some objects in my scene. In unity i know we can make two cameras with object masking and apply the post processing to the camera that sees only the objects intended to be blurred. Can something similar happen in unity ? I have a bout 100 dots but id like to blur only maybe 50 of them with a DOF affect.

etcc…
