MAE for every time-step using multistep modules for timeseries forecasting

Hello, I have been following the next example : Time series forecasting  |  TensorFlow Core
I am now implementing the multistep LSTM model and trying to compare its performance to a singlestep model. Therefore i was wondering if it is possible to obtain the MAE for every timestep prediction. Indeed, multi_lstm_model.evaluate averages the MAE over all time steps and i cannot find an argument for model.evaluate that does this.
Thank you very much
