Duplicate, group or re-use custom form fields.
One example, in a single custom form we ask several currency questions. But I can only use a currency type (USD, EUR, etc.) drop down once. We have to recreate and rename it each time for each question. This is not ideal nor is it practical and is just one example of many.
It would also be convenient if you could group custom form fields, either by group or company, so that other teams, groups, etc., don't run the risk of overwriting fields.
