Personalized Workflow notifications based on approval

Content

Hello,
we would like to have different messages sent when a user requests a non catalog learning item depending on the status of approval.
As of now, the notifications are handled by the reports LearningRequestApprovalReport , LearningRequestLearnerReport and LearningRequestCancelReport of the folder "Shared folders\Custom\Human capital managment\Workflow notifications".

When a non catalog item is requested one mail is sent to the manager that can approve the learning item:
Action required: Requested Learning for <Name of course requested> from <Leaner Name>

After approval another mail is sent with the confirmation of the approval:
Approved: Requested Learning for <Name of course requested> from <Leaner Name>
