# python and quantlib - setting futures priority

In setting up a curve using deposit rates and futures in python, is there a trigger which allows one to set when the futures start?

Looking for something similar to DepoFuturesPriority in the QuantLibXL version - which allows for AllDepos, DeposBeforeFuturesStartDate, DeposBeforeFuturesStartDatePlusOne, DeposBeforeFuturesExpiryDate?

Right now I am using

rate_helpers = depo_helpers[:4] + futures_helpers + swap_helpers


which basically uses the first 4 depos but until the expiry of the last depo not until the start of the first future.

Any help or suggestions appreciated
