ITAC -- Naming generated .stf file to differentiate runs

Hello, 

I am using ITAC from the 2017.05 Intel Parallel Cluster Studio. I issue a number of mpirun command lines with ITAC tracing enabled. I am trying though to assign specific names to the generated .stf files so that I can associate the .stf files of a particular run with the corresponding mpirun command.  

How can I do this? 

Is there any option as we have for the statistics with the I_MPI_STATS_FILE?

Can I do something like  

mpiexec.hydra ... -stf-file-name MPIapp_$(date +%F_%T) ... ./MPIapp 

Thank you!

Michael
