Min days before booking in Complex Tariffs (multiply periods)

Hi!

I have some problems with Comlex Tariffs.
Customers In our hotel can book rooms only for two weeks (min) before arrival.
When I set "Min days before booking" to 14 days in component options it works.
But we have different tariffs for some periods. For example, May - 100$, June - 150$. I created 2 tariffs for this periods (05/01 - 05/31 and 06/01 - 06/30). Now when I try to book room with second tariff, I can pick date only from 15 June (or less, if I change option "min days before booking") in datepicker. But I need "min days before booking" only from today, NOT from tariffs period start.
Please help to solve this.
Sorry for my english. Thank you.

Done
