### Open several psspy-modules from Python

Is it possible to have open several sav-files in Python, and do operations on them in parallel. For instance, I may want to run load flow analysis on two different load scenarios, or different topologies for the same power system and compare them. I would like to do something like:

psspy1.fnsl()
psspy2.fnsl()


And compare the branch flows etc. Is this possible? Any help is greatly appreciated!
