How to use harmonic restraint parameter for 2 selection of atoms

Hi, NAMD users:
I want to apply harmonic moving constraints to 2 different parts of atoms, one of which shall be restrained at a certain plane of a fixed z coordinate, while the other part shall be assigned a constant velocity.
However I am confused about the setting of NAMD harmonic constraint parameter, it seems that I can not assign two different motion of atoms if I use "movingConsVel" item.
How can I define a moving restrained and a position restrained atom selections simultaneously in NAMD running configuration file?
