The forecast feature is great but could be improved by allowing exclusion of certain dates. For example, I don't want to include holidays in the data I'm forecasting from. Additionally, our weekend volume pattern is completely different than our weekday volume pattern. So when I forecast and it includes all days of the week, it makes it seem like the volume during the week will be lower than it is (due to the weekend volume bringing the average down).

My workaround was to make Explosions by day of week and/or create a calculated Group attribute for Weekdays vs. Weekend days and make an Explosion from that. However, it would be much easier to be able to exclude certain days of the week and holidays/other exceptional days using filters. Otherwise I have to create/edit a Group attribute for everything I want to exclude.
