Hello, it's possible using scon or /scid
/scon works with connection number, the first status window is connection 1, the next one 2 etc.
/scid works with connection ID, the first status window may have any ID, like 2, while the second status window may have 1
Inside your event, you can use $cid to get the current connection ID, there are no $con equivalent to get the connection number, but it can be scripted with a loop over $scid or $scon.
You need to find a way to identify your network1 via its connection id or number, and then simply use in your event, /scid <network1_id> | msg $chan ... (or /scon <network1_Nth_status window)
Watch out, /scid <id> msg $chan ... is a syntax that works, you can include a command in /scid to be executed on the given connection, but this double evaluate your parameter, so make sure to use two differents commands there for /scid (or /scon) and /msg
