Disable certain channel in C line

[Palinkat]

Hi All,

Is there a way to not allow certain channels from a share in the C line.
I read here Providers can be disabled as follows:
C: server.noip.com 12000 username password no { 0:0:2, 093b:0 }
What if I need specific channels to be disabled rather than the whole provider.
I tried the following example:
C: server.noip.com 12000 username password no { 0:0:2, 093b:000000:2581 }
But it doesn't work. Any other way?

Thanks for the help.
