MFS Telegram Channel Assignment

All,

I'm experiencing an issue where we have two MFS Channels (A & B). Channel A is outbound communication (MFS to WCS) and channel B is inbound communication (WCS to MFS). Our outbound channel traffic at times is congested and I would like to move a telegram to a new channel to help clear up the congestion however I'm having a difficult time locating the configuration where telegrams are assigned to a channel.

Can anyone point me in the right direction?
