Thanks for the reply Adam. That should get the job done (with a filter on that formula). I’d be changing the filter text often in the actual application, but I suppose it wouldn’t be much more effort in practice to edit the text in the formula column vs the filter contains field value.
Have you ever seen a feature request like a checkbox to go along side a ‘contains’ filter value field for case sensitivity? That would be ideal, but I feel like if that haven’t added something like that by now, it probably hasn’t been requested much.
