I have searched the community. This is not a new idea/request. I can see technical responses why this isn’t possible with Skuid.
The desire is to do a client-side filter of a UI Only field. Without this ability, we are forced to create a database view with the calculated field and then use the view as our data source rather than the table. It works, but it is a lot more painful than adding a UI field and doing a client-side filter.
