RFx reponse with different item currency

Hi,

RFx is created with 3 line items and the currency is USD.

Now the supplier wants to use different currencies at the item level in the RFx response.

For example: Item 1 with currency USD, Item 2 with EUR and Item 3 using SGD.

Currently the currency field is not editable in the RFx response and hence it is not possible to change the currency directly in the item.

Is it possible to achieve this functionality or this is the standard behavior in the RFx response?

Thank you in advance!

Regards,

Aswini
