How to change the transaction labels on the Fluid Approval tile

When using the fluid approval tile that is delivered in PeopleSoft, each of the transactions (e.g. Purchase Order, Voucher, Requisition, Expense Reports) can all be approved on the same summary page.

Each of the transaction types have their own transaction summary label, e.g.:

Vouchers show up as BUSINESSUNIT - VOUCHERID - INVOICE ID - OPRID

Requisitions show up as REQUISITIONNAME - BUSINESSUNIT - REQID

How does one change the transaction label on the summary page to add additional fields, e.g. changing the Voucher to be BUSINESSUNIT - VOUCHERID - INVOICEID - OPRID - INVOICEDATE - ORIGIN ?

I've looked at the Page Composer but that only allows me to update the transaction details/page layout once I actually select the transaction (e.g. Vouchers) to be approved and does not allow me to configure the overall summary page
