Customer Account as a Standard Object in App Composer

Organization Name (Required - If you are an Oracle Partner, please provide the organization you are logging the idea on behalf of):

Paychex

Description (Required):

My organization requires a DCL on a Custom Object for associating the record to a Customer Account. This does not appear possible without a Customer Account standard object.

It appears there is a standard object called 'Account', but this object is displaying Party information, not Customer Account. Since a single Party can have multiple Customer Accounts, this object is not useful.

Does a Customer Account standard object exist?

Use Case and Business Need (Required):
