As for the sequence ID question, you can supply your own job-uuid
header when you send the bgapi-command

bgapi show channels
job-uuid: 1234

This was not available from the script mods when I checked so I added
it to latest build.
example in perl but true in all swigged langs.

my $command = shift;
my $args = join(" ", @ARGV);

my $con = new ESL::ESLconnection("localhost", "8021", "ClueCon");

my $e = $con->bgapi($command, $args, "my-job-id");
print $e->serialize("json");


returns:

{
       "Event-Name":   "SOCKET_DATA",
       "Content-Type": "command/reply",
       "Reply-Text":   "+OK Job-UUID: my-job-id",
       "Job-UUID":     "my-job-id"

}
