Hi ExB community!
I am building an application that includes a filter based upon a field of years ("2016 through current"). I am trying to group the years for 2016 through 2019 under a single label such that those four years will be selected if the user select that label (such as "Pre-2020").
Using the "Predefined unique values" option in the SQL Expression Builder, I can specify the label for the years 2016, 2017, 2018, and 2019:

Unfortunately, the Filter Widget does not combine those years into a single option, but instead lists them out individually, with the labels repeated. And each label still only applies to the respective year to which it is assigned.

I am hoping someone can help me point out what I am missing, so that the Filter Widget knows to group the four years as a single option...or maybe confirm that this SHOULD work, but is actually a bug.
Thanks in advance!
Mark
