Currently, we can filter by any set of "x" filters which we can toggle on or off. Such as, a task in a project with certain criteria, perhaps it for type of ad medium, print, social, outdoor. Please let us have a second, separate capability for "y" filtering. In this case, we could filter for those x filters, but then have the ability to toggle on or off a separate level of filtering. For example, let's say filter y is about geography... so we could toggle on everything in filter x, all or some of the ad medium and then decide we want to add a regional filter for any of them ... all outdoor, but only in EMEA.
I realize we can do this by creating specific x filters, but we're limited to the number of filters per calendar (10, is it?) and this would extend the Calendar capability greatly.
