Transmission in router. Stop at the end torrent

[pikomule]

Hello, I have installed transission a router Comtrend 536+. Anyway, if I have many connections saturates and several active torrent. I have connections and limited to 60. I want to finish downloading a torrent, it stops, not to share, and start with the next torrent. I only want one active torrent

You know tell me how? I can not find the right options.

Thanks and sorry for my English, use translator

these two options and had on, and when it finishes a download, share starts but does not start the next torrent, only remains active is that this sharing.

I know that P2P is shared from this router I can not, but from the PC if I share
