How to add a new line with a new subtotal on Paid section of the order page

Hi, I want to add a new line on “Paid” section of the admin order page with the outstanding price. Is that possible?

“totalOutstandingSet”: {
“shopMoney”: {
“amount”: “-10.0”
}
},

as you may see, there’s a difference between Total and Paid by customer of 10 USD that is the totalOutstandingSet.
