!seen tracking, how do i disable it for 1 channel only?

[ugluk]

i like the !seen tracking. however there is one network i'm on, and i'm in several channels, most are small ones. but im also in 1 big channel, and i'd like to disable !seen for that channel, but NOT the other chans.
i would like invision to track all the channels, just not REPLY to a !seen request made in that said channel... (but still track it!!)

how do i do this? i recon i'd have to edit the script myself? if so any ideas or suggestions on how to go about it.
any help would be appreciated greatly!
