The new Availability setting are AWFUL

Due to the Jewish Holiday season, I will have different work hours for each week of October.  There is no longer any easy way to “override” the regular calendar with an easy click.  For example, I don’t normally work on Sundays but need to be in my office this Sunday.  NO easy way to simply open up the Calender for a “one-off” work Sunday. PLEASE go back to the old version-it was SOO much better.  If not, I am switching to another program.
