How to select file to download from .torrent

[[.::MDT::.]]

Hi, I have a question:

when I open a file .torrent I can choose which file (it contains) to download; if I choose for example to download only the first file the download starts, how can then I choose to add more files?

I can't find how to add new files from the torrent once it started!

Please help me, thanks!
