Its not an uncommon practice to bill certain cost e.g. expenses based on actual costs and third party invoices and receipts - its quite feasible that a consultant might visit several countries on a global project and have to pay for meals, taxis, flights etc, in different currencies, and he may also have expenses in his home market, and his time may be sold in another,  currency, In countries where exchange rates are volatile even imported materials may be priced as 'cost plus x%"

However, this requirement is not supported currently I any Ax version.

Having to manually convert all RFQ quote lines,  and actual values to a project contract currency adds complexity and is prone to error so some enhancement here would be welcome
