It is really disjointed user experience to have so many different screens to handle cascading drop downs. It would be great if we could set a input screen to refresh all fields on a change of a value on any of the screens. It may involve a lot of back/forth to see the outcome of the options selected.
I would love the following to be on ONE screen:
Business Unit: <options: static list> Location: <options: condition based on BU> Device Type: <options: condition based on BU> Device Number: <number 1-99 - visible only if DeviceType=VMT> Computer Name: <value baed on Location/DeviceType/DeviceNumber> - READ ONLY.
This would be something like RefreshOnChange="True" for an Action input type. When a field is changed, that the conditions for all the subsequent fields are refreshed, conditions checked.
