Well.. if you need one at the moment.. heres a quick remote alias.. just use it in the same way you would $ignore: $nsignore(id)

alias nsignore {
set %i 1 | set %c 0
while %i <= $ignore(0) {
if ($ignore(%i).network == $scon($cid).network) { inc %c }
if (%c == $1 && $1 != 0) { return $ignore(%i) | halt }
inc %i
}
if ($1 == 0) { return %c }
unset %i | unset %c
}
