Is it possible to audit changes made within the Work Schedule Assignment screen?

Summary:

We would like to be able to audit changes made by users to the Work Schedule Assignment screen.

Content (required):

Using Tools -> Audit Reports, does anyone know which Product/Business Object this data is held against?

I have tried Absence Management and Global HR but this is not returning results as expected.

We don't currently use the Time & Labor module, but on checking Setup & Maintenance -> Manage Audit Policies it doesn't appear that the work schedule can be audited from here either.
