Link Between task and Notes/Notes Evernote/Files

Dudes,

I would like to have the option to link some Note, or Evernote Notes or a File to a specific Task. Not only linked with the project.

I mean a lot of my task start from a note, a file or a evernote note. So I have a lot of task to do, a lot of notes but is difficult to link a task to a specific note.
