I tried the
alias "MobT" "mob1"
alias "mob1" "ai_reaction_delay_idle 99999;ai_reaction_delay_alert 99999;alias MobT mob2;cc_system_message Pie-Distracts-Them"
alias "mob2" "ai_reaction_delay_idle 2;ai_reaction_delay_alert 2;alias MobT mob1;cc_system_message mob DelayOff"
and i entered them one at a time but it still won't delay/disable the AI when i bind it to a key.
