Hiding the PO amount from the PO output (pdf)

How to handle cases when we don't want the supplier to see the PO total amount

Hi,

we have a business cases when we don't want the supplier to see the total amount of the PO. Is there any way how to hide it? The reason I posted this to Self Service Procurement forum, not Purchasing, is that we hope to find a solution that can be done by the requester (without buyer's manual work)

For example, we order some construction work. We want to create the PO for a sum of 50000,00 EUR (estimate), but we don't want that the supplier sees the sum we have "reserved" for this work.
