CST - Line, surface values and integrals in post processor

Hi everyone. I am just beginning with CST Studio Suite and was hoping to find numerical values, along lines or across surfaces, for example, in the post processor. In the actuator tutorial from the learning edition, can I find the net flux crossing the gap or perform a line integral of H·dl, to compare to current? Please point to a manual if I'm missing a basic feature. Thanks very much!
