How to Add Additional Locations to Oracle-Delivered Expense Location LOV in Fusion Expenses?

Hello Experts,

We are working on the Oracle Fusion Expenses module, and we have a client requirement related to the Expense Location field.

Issue / Requirement:
The client operates in multiple locations that are not available in the Oracle-delivered Expense Location LOV during expense entry. Because of this, users are unable to select the correct location while submitting expense reports.

Business Need:

• Additional business locations must be selectable in the Expense Location field.
• This is required for accurate expense reporting, compliance, and internal tracking.
• The solution must be Oracle-supported (no unsupported customization)

Any guidance, documentation references, or implementation experience would be greatly appreciated.
