Description - Allow lookup field results to serve as the basis for display logic within a custom form. (Especially $$HOST-based fields)
Why is this feature important to you - This would bring external lookup fields to parity with other selection-driven logic on other field types in Workfront.
How would you like the feature to work - When a user makes a selection in an external lookup field, that field should be added to the list of possible display-logic and skip-logic choices in subsequent fields within the same custom form. Just as dropdown fields do today. This allows for greater control and intelligence within a custom form design process to ensure users are guided to selections that make sense for a particular end-goal.
Current Behaviour - External lookup fields are not recognized by the system as valid choice for which a user can initiate display or skip logic.
