Custom hook for lot generation in oracle fusion cloud

We have a requirement to generate a custom lot number based on the customer requirement. In EBS R12 we have a custom hook (package) which is used to generate the lot number. Do we have the same kind of feature or data base available for Oracle fusion cloud.

Below package is available in EBS R12 for generating the lot prefix as a standard functionality. Where, custom code can be written, generate the lot prefix.

PL-SQL Package: user_pkg_lot
Function: generate_lot_number

Please let us know in case any such standard functionality is available in fusion.

Thanks
