Default Superimposing 2 Velocity fields For Model inputs in Comsol

Hi every one
Im Trying to use a superimposed Velocity Field which i did get it from solving 2 Laminar physics (I solved them in two different Studies called Study 1 and Study 2 at Stationary mode) as the Velocity input in :
Transport of Diluted Species physics>Transport Properties 1>Model inputs
But there is a is not possiable to choose the both Velocity Fields together!Comsol only allows us to chose a specific Velocity Field from a specific study (For example i can only choose the velocity field of Study 1 (spf) or Velocity field of Study 2 (spf2) and not both of them together.)
I want to know if there is a way to superimpose those velocity fields together and use them as an input for solving the Transport of Diluted Species equations?
I have already figured it out a way to superimpose the velocity fields by exporting data from Results>Data sets and importing those data as 3 interpolations (each for one of the Superimposed Velocity field components like u+u2) but still I dont get the correct results.I would be happy if you help me with this problem

Many thanks in advance for your help
