Filter Weekends

Hi all, can price data be filtered such that I only show candles starting at 21:00 UTC on Sundays and ending at 21:00 UTC on Fridays (similar functionality to the Filter Weekend check box accessed via File > Database Settings > Intraday Settings)?

I trade Forex and I'm using AmiBroker for back testing. This functionality would allow me to only show candles when my market is open (i.e. the same view as I have with my live account).

Thanks.
