Update Tokens during program run in WebSockets

Hi
My use case is below
I have a program that initiates WS with a list of tokens and performs a number of actions on each tick. During execution I need to add additional tokens to this the tick. How can this be done? Just updating the tokens doesn't update the tick list.
Is this even possible or do I need to start another WS call for the new tokens which is a dirty way to do it. Hope I am making sense. Let me know. Thanks.

Pseudo Code:

def main()
	def on_tick(tick,ws):
		#Do a lot of things based on tick..
		# While doing some check in a "new thread" i find that i need tick data for a new script
		# How can i update the tick / tokens to let WS know that a new set of tokens has arrived and 
		# real time ticks are needed against this new set?

	def on_connect(ws):
        	ws.subscribe(tokens)
	        ws.set_mode(ws.MODE_LTP, tokens)	
	
	kws.on_tick = on_tick
	kws.on_connect = on_connect
