I'm trying to create a new field that displays the last item select from another Multi selection Choice field. We currently use a choice for Portfolio Years which show as a string of values selected.
Multi Value lookup has a length property to work with but I want to just use the last value of the Choices selected. I don't see a properties or functions hyperlink in the learning center for JSON Formatting.
If I could do a simple split and use the last item in the array.
i.e "2022, 2023,2024" Show just 2024 in the new column.
