Easier way of forwarding phones during business holidays

I seem to get lost in the custom rules. Although I manage in the end, it would be much nicer to just pick multiple different days of the year and say "these are bank holidays / business holidays, do this with the phones..." etc. Rather than add multiple different custom rules. It may be the way we have our queues but right now it is very confusing to do, and to have a separate place solely for holidays each year means we wont forget to have them in place
