Need to modify AP approval notification seeded template

Hello team,
Our customer has a critical usability request for AP workflow notifications. They need the workflow attachment to be directly visible on the main notification page (within Worklist -> specific notification, scroll to the last), rather than requiring navigation through the 'Actions' dropdown and 'View Approvals' option. The current multi-click process is seen as inefficient and comparable to viewing the entire invoice. Is it possible to embed the attachment directly into the notification display to eliminate these extra clicks. We understand that modifying the seeded workflow notification template might be the solution. Could you please confirm if this is feasible and
