Is it possible to set subjectline based on a html upload?

Hi, 

Often times I need to import a lot of html files with translations of the same email.  Is it possible to include the subject line in the html file that is imported so that it is automatically set?

Over here translated html files are generated with a script and then imported manually.  It would be great to not have to open the right translation, find the subject line in that translation and copy paste in to the editor but instead have it included in the html when this is generated. 

Hope someone has an answer!

thanks!
