Import titles from file on computer to IMDb list

I have a file stored on my computer that contains a bunch of movie names and IMDb IDs that I've watched (456 to be exact) and I want to add them to a list on IMDB. Obviously, going through my file and adding each title one by one would take forever. I think it would be a nice feature to be able to import titles from a file on your computer. Something just like a text file containing an IMDb ID on each line, like so tt0289043 tt0381849
