Set additional command line arguments

I will start off with that I am more familiar with Unity than I am with UE4. I am currently trying to use the new editor utility widget to change my file path using the console. My goal is to capture a movie using a new file path. If there is a better way to go about this please let me know. Should i be doing this in C++? Should I be modifying the editor? Should I make a plugin? What is the best way to do this in UE4?
