Tvheadend

Hello there.

I was wondering if there is some hiddend kind of channelid for a channel that is currentley beeing watched or recorded?

For example: http://user:psw192.168.1.1:9981/stream/channelid/current#

What I'm trying to do is have a .m3u playlist file that I open with vlc that always can watch the current channel that is tuned.

I'm guessing this is not possible so my followup question is if there is a way for me to manually put a file in http://192.168.1.1:9981/stream/channelid directory. Or some other directory that a user with only "stream" rights can access.

Thanks for any help.
