Ensuring your default Cost Center or PO numbers are configured is important because these defaults will apply for all Team gift requests unless changed for a specific project or initiative by an Admin.
Gift Senders cannot set or edit Cost Centers or PO numbers, so whatever is set as the default will always apply for them unless an Admin has chosen to override the default for a specific initiative. For more on overrides see article here
You will see your Team's defaults indicated by a ⭐ in the Billing Details.
To change defaults, just click ‘Set as Default’ when hovering over the desired cost center or purchase order number.
