AR- Customer dependency on Transaction Type on Create Transaction page

Summary:

We would like an enhancement that allow us to make Customer search dependent on Transaction type

Content (please ensure you mask any confidential information):

When a user selects a specific value in the "Transaction Type" field on Create Transactions page, Customer "Bill To Name" should display values(customer names) that are restricted to that Transaction Type.

Upon selecting the "Transaction Type" , "Bill-To Name" field should dynamically update to show only the relevant customer name, this may be achieved by a custom lookup table or groovy script to map Bill-To Name and Transaction Type (any other suggestions appreciated).

If above is not feasible then while saving the transaction in AR invoice screen user should get a custom message that transaction type is not selected corresponding to the customer selected.
