I don't enter this area muchm but this I can answer
To enter the MAP channel, type in what you see in the upper left corner into the onject name field.
EX: ATLS1 [0,3]; replace ATLS Trigger TRS19 2 with ATLS1 [0,3]. It might require you to enter the properties twice before it goes into MAP mode
To remove MAP mode, just clear the object name field and enter the properties twice and it should revert back to session mode.
Cheers
