Where is the justification for a budget override request stored?

Whenever a user creates a budget override request, he/she needs to enter a justification or reason for the override. The name of the field depends on the transaction for which the request is created, either a GL journal, an AP invoice, a Purchase Order, a Purchase Requisition, …

However this information seems to be lost in space/cloud. First of all, we would have expected it to be included in the notification that is send to the user that is requested to approve the override but that notification is almost empty. It has no information on why the override was requested.
