In List is it Possible to Change Between Running Times of a Movie?

Hi, I have a public list of all the movies I have watched. I will usually export my IMDB list into an Excel file and keep track of all the ratings, running time, number of ratings, IMDB ratings, and everything. 

Yesterday, I watched Troy for the first time. However, I watched the director's cut for the first time without knowing it. The director's cut is longer, by about 30 minutes. When I add Troy to my list is there a way to change the running time to the director's cut which is included on the IMDB page, but it is not the default time? This way when I export the list I do not have to manually change it. Having to manually change it each time would not be preferable. 

List is Below.
