Maybe I’m late to the party on this, but I haven’t seen anyone else mention it. I just discovered that OR filtering is still available. Everyone clamored for AND filtering, but I thought it was a little odd that they dropped OR filtering when they added AND. Turns out, they didn’t drop it.
If you add rows to the custom filter and select the same property in each (Collection, for ex.) row, the filter evaluates the rows as an AND filter.
Select multiple values on a single custom filter row by repeating the action:
While viewing the Custom Filter UI, click the Value field once and pick the first value. Then click the Value field again to pick the second (or third, etc.) value. These will be treated as an OR filter.
I originally posted this in a thread I had started about a problem, but I think it deserves its own thread to let people know about it.
