Description - Add the ability to create validation rules (As a Sys Admin) using Regular Expressions or some other validation technology.
Why is this feature important to you - Ensures you are getting correctly typed data
How would you like the feature to work - Whether the field is required or not, have a validation rule field that allows regex formulas to validate if the value entered is acceptable as a response.
Current Behaviour - No validation other than required or not is available.
