Automatically adding file name to TM fields

Hi all, 

If I want to know which file(s) a particular TU comes from, I know I can manually enter the file name as a "Text" field under "Fields and Settings" in the TM settings prior to translating the file.

Is there a setting somewhere that would tell Studio to automatically add file names (to avoid having to add a new text field to the TM every time in projects with a lot of files)?

Thanks!
