Is there an API or FBDI in the pipeline for future releases to maintain account rules in COA mapping

For mapping Chart of accounts, we will use both segment and account rules in the Manage Chart of Accounts Mapping task. Oracle documentation states that the segment rules can be maintained by FBDI. However we have the need to maintain high volume of Account rules to fulfill our requirement.

Does Oracle fusion have API to maintain the account rules in Manage Chart of Accounts Mapping task? If not, is an API or FBDI in the pipeline for future releases?
