importing from a csv to populate a field in a bank file.

I’d like to write a tool that imports text from a field in a .csv file, and populates that string into a field in a uasset file. Specifically; I’m trying to import strings of dialog into a wwise bank uasset file subtitle field.

How should I approach this? Can I write a standalone app that can undress the uasset file? Or should I be exploring the plug-in/commandlet route?

If someone could just point me at the best way to tackle about this, I’d appreciate it.
