Is it possible to view current item on-hand Quantity in parts requirement HTML UI?

In the HTML page of parts requirements, which is accessible by click on the parts button in the SR form, is it possible to view current on-hand Quantity for each line?

This is very needed by the inventory user to check the on-hand instead when click on button save if the item is not enough in inventory it will give error "Reservation is not created due to insufficient Quantity".

Thanks.
