How Can I Add A Source

[vikaspell]

I was downloading a file and suddenly after quiet a long time of download it never find any listed source online.
However when i search for the same file i find it with th exact same file name and the size.
Is it posible for mr to add the source in the already partially downloaded dat as i dont want to restart all the way from byte Zero(0).
thx
