teach me the new enhanced input action system

hi i am new to unreal and my question might be a bit dumb so i apologize in advance. Is it possible to add the mapping context to a custom player controller blueprint performing step 7,8 and 9 in the player controller blueprint rather than in the character blueprint?

I know Unreal wants us to do it that way cos there in one of the starter projects “Stack O Bot” it is briefly mentioned in the BP_bot character blueprint
