Personalize / Customise Purchase Requisition Approval Notification - 12.1.3

Hello Oracle Community.

Client requires the ability to view a 'Supplier Item Number', Per Line Level, in the Approval notification, as seen below:

I have ordered 1 'Yeet Stick'

In the Purchase Requisition, the Supplier Item Number for the 'Yeet Stick' is recorded as 'Javelin_Item_Long_Range_'

I need this Supplier Item Number displayed in the Line Level marked in RED.

Can this be done? And if so, can I be linked to the correct guide to perform the Personalisation / Customisation or be guided through the process to set this up?

Additional fields have been requested to be added here, but will review this customisation as a start.
