OData - currency of money field

Hi experts,

For a business case I want to retrieve opportunity data from C4C via OData (or SOAP). This can be easily achieved by doing a rest call to the following url: https://my[tenant].crm.ondemand.com/sap/c4c/odata/v1/c4codata/OpportunityCollection?$format=json&$select=ExpectedValue

But the problem is with requesting the Expected Value of an opportunity that all values will have a different Currency(code). Because they are stored in the system with their own currency.

Is there a way to retrieve all Expected Values with the same currency, for example USD?

The reason I think it should be possible is because in the Opportunity Header datasource you can choose the main currency and all values are recalculated to that currency.

A standard filter is not an option, because then only the ones that are valid are returned:

$filter=ExpectedValue/currencyCode eq 'USD' only gives the Opportunities where the currency of Expected Value is USD.

Does someone have an idea?

Thanks!
