How can I change the label of the PO Number on the Manage Transactions and Transaction Activities

Summary:

I want to change the PO Number label to 'EXT/CONSOL INV ID' on the AR Manage Transactions and Transaction Activities screens. I was able to make similar changes in other areas using the Sandbox Composer tools, but I’m unable to apply this change at the AR Manage Transactions and Transaction Activities level. Could you please suggest how to proceed with this?
