Default Change the Inlet BC profile for each timestep

Yagriver is on a distinguished road
I would like to run an air-water simulation of an inclined plate where the water film is flowing down a channel of an specific slope. At certain point there will be an injection of salty water for which I plan to use an additional variable.

My idea was to do 2 simulations.
  1. First, before the injection, the inclined channel will be simulated using a translational domain for a certain time, saving the BC profile at the outlet for every timestep.
  2. Second, run the simulation of the channel with the injection, applying the BC profiles at the inlet obtained from the previous simulation.
My question is: Is it possible change the whole Inlet BC profile for each timestep? (of course both Volume Fraction and Velocity). I would also appreciate any other ideas

Thank you all!
