Adding a new dependent variable in a 2D axial symmetry NS problem

Hello
I'm working on a particular case that requires to add a new dependent variable.
Actually, my problem is a 2D axial symmetry one. So i have to calculate the radial and axial velocity and the pressure. They depend on the r and z coordinates only. However, in my problem i also need to take in account the azimuthal velocity that also depends on the r and z coordinates only.
So i want to add this azimuthal velocity and the corresponding equations in the Equation System Subdomain Settings ( i need to add an equation that correspond to the navier stoke equation along the azimuthal coordinate).
Is it possible to do this ? (because when i'm adding a dependent variable in the model navigator i get an error)
Thank you for your help
