ADD Default Customer Registry ID and SITE Bill to and Ship to Numbering according to the BU's or LE

There is a business requirement Based on Legal entity or Business Unit the Automatic Customer Numbering should be opted.

For Example if the LE1 or BU1 is trying to create a customer. The Registry ID should start from Prefix BU1001 or LE1001 same goes to site level (Bill to, Ship to) also.

Please suggest if there is a way to achieve the same.
