Can we make customer dependent item in LOVs in Oracle Demantra

Hello Guru,

We have requirement that if we create any program in Demantra using Standard method or Custom where we can go and see the list of items in LOVs. Here Customer Wants is that if we put any customer member in Demantra Tree Structure to populate LOVs Since customer is level here, Can we get the list of items only for those Customers? If we move to another customer, It will pull up those items associated with that customer. Is there any way to get those items based on Customer dependency?

See Below Example:

1)If I enter to into the screen Customer A > Item Y
