Automate Putty

i have a windows laptop running 10 putty session. For now, i open each putty manually and set up the log to print and save to a file in a defined folder. When i connect 10 usb - the com port number is changing. I want to fix the Comport's to a defined numbers for ever. What need to be achieved is, 1. Need to define the COM port's of the laptop 2. Need a one click solution to open all the defined 10 COM Port's and print/save the logs.
