Is it possible to create custom fields in Compensation Change Statement worksheet?

Summary:

Content (required):

Hello experts,

in the compensation change statements system page (please, see the attached screen) our customer want to create a checkbox where the manager can flagged when downloading the employee letter in order to know which letters have been already downloaded and those not downloaded yet. Is it possible to add a custom field inside that page?

If not, how could the manager track the downloaded letters? Is there a BI transaction of it?

Thanks in advance for your time!

Kind Regards,

Valerio
