Customize(Replace) Standard Spreadsheet templates embedded in Application Pages with custom ones

Summary:

Many Application pages (such as the Workforce structures pages for Jobs, Locations and Departments) have the option "Manage in Spreadsheet" that allow to create and update the business object using HSDL. The templates embedded in the Application pages are anyhow seeded ones and rarely can be used as is: not all the fields are added by default to the seeded templates and also any DFFs/EFFs are missing.

Seeded HSDL templates can be copied, but is there a way to replace the seeded templates with custom ones so that from the "Manage in Spreadsheet" embedded in Application pages the custom version of the Spreadsheet is launched instead of the standard one? A sort of customize future like the one available for BIP reports.
