Transaction Console WorkFlow notifications(FYI And FYA) in HCM

Hello Everyone,

we have a few requirements from customer regarding the changes in FYI- For You Information and FYA-For your Action notification templates which user receives via email or as a notification.

Requirement :- Adding a new field to the notification (i.e., in template).

Now my questions are:-

1) Can we add a new field to the existing standard template..?

2) If we can add then how should i find the exact template which is being trigger after change.?

3) what are the steps to add the new field to the template.?

also request the community members to share the relevant documents if any available
