schedule update_universe?

Is there an elegant way to schedule update_universe? For example, say I wanted to only update the universe monthly/quarterly. Can schedule_function be used directly? Or would I need to use a context flag? Other?

Recommendations on the best approach welcome.

I schedule the context flag, something like,

 def update_universe_buy(context,data):  
        context.buy_day = True

def before_trading_start(context,data):  
        if context.buy_day:  
          update_universe( list )



Hope that helps,

I think this question will be moot when Quantopian 2 ships to production.
