IWR1443BOOST: Modifying UniFlash python code

Has anyone tried to modify the UniFlash python code, after creating an executable from Uniflash?

I want to use the RTS pin of a USB UART cable to toggle the SOP2 pin. 

I created the executable zip and tried to modify the Python code in mmWaveProgFlash.py.

After a lot of crashes when running the modified code, I found out that I can't change the number of lines in the python code.

So I had to replace a comment in the code with the desired command. This doesn't allow me to exactly achieve what I want.

Has anyone experience with this, or should I ask this in the CCS/Uniflash forum?

Thanks!
