Creating dummy movie files for PLEX

Hello

I have a list of movies, roughly 1000 in a text file, I would like to catalog these within PLEX by creating a dummy file with the movie name, year and extension of MKV.

I do not have the movies as physical media files in Plex. This is to be able to browse the collection and look at the metadata and then download the movies i want to watch and gradually replace the dummy files.

Instead of creating them or typing them all out, anyone know of a tool that will automate the task

thanks
