Is there a way to check Condition right after join NPC waitingroom

[Alexandrite]

this is example of my currently use

OnInit:
	waitingroom "Waiting Room",20,"Peter S. Alberto#job_league::OnStartArena",1;
	enablewaitingroomevent;

	end;

OnStartArena:
	warpwaitingpc "job_prist$",24,44;

	attachrid $@warpwaitingpc;

	if (BaseJob == Job_Priest) {
		goto OnStart;
	}else if(BaseJob == Job_Acolyte){
		donpcevent "Zombie_Generator#job_league::OnEnable";
	}

	disablewaitingroomevent;
	end;
OnStart:
	enablewaitingroomevent;
	end;

This Code is worked...

 

But it's wrong order because this code already trigger after you got trigger "warpwaitingnpc" and then you "attachrid" later

 

I would like to make a room condition right after they enter the chatroom

as if when you enter the room if(BaseJob == Job_Priest) or if(BaseJob == Job_Acolyte) or if(BaseJob == XXXX)

I mean I want it check in the begining of when player enter the ChatRoom

And I would like command to click the player that not met condition out of that Room too

 

Is it possible ?

I mean i want to make a room that people who met Condition only who can enter ?

Thank you and sorry for my bad endlish
