Personalizations - How do you personalize a List of Value form/view?

In the past we have used custom functions to modify list of value forms such as the serial number LOV in all inventory transaction views (receipts, misc transactions).  Example: When performing an intransit receipt for serialized product you select the serial number LOV without entering values, a find view is popped and you are forced to enter data and/or enter %, and then you hit find to get data returned. With a custom function we were able to force the LOV to return all serial numbers available on that intransit receipt without requiring the user to enter criteria data or %.
