How can i pass input to lower priority imc when higher priority action use trigger with chorded action

[dda11479c5e14fc6ab6fc5e49ddd0054 (啵啵啵很忙)]

I have to input context map:
1.IMC_Play(lower priority):

2.IMC_Debug(higher priority):

when I pressd “left ctrl + p”, it will trigger IA_DebugSwitchAIAction without trigger WalkAction.
How can i trigger WalkAction when i only pressd “left ctrl”?
