Would like to see this implemented with RegEx field validation as a proven method to implement complex validation rules against input data. Validation would be best handled in the UI to provide realtime guidance to the end user when inputing data.
Here's another example where a link leads to nowhere. All the links in this thread lead not to idea pages but to a documentation page (https://experienceleague.adobe.com/docs/workfront/using/home.html). Can we please get these old links fixed and pointed at the correct pages? Every thread I click on has this issue.
