Does particle lift force being considered in the particle-fluid momentum transfer?

I am using the DPMFoam. For the particle momentum source term Sp in the N-S equation, I know it is an integral of the particle drag force (and pressure gradient force if it is considered) in each cell.

However, if I turn on the lift force for particles (fluid to particle), will the reactive lift force (particle to fluid) be added directly to the calculation of Sp, to affect the fluid phase?

The lift force is added into the momentum source term, the same as the pressure gradient force.
