Foreign Exchange trade message: FX trade with split or home currency rate additionaly to the trade currency rate

Imported from previous forum

My Question to the product FOREIGN EXCHANGE (Foreign Exchange Trading): How is it possible to handle split rates or home currency rates for usance deals. I didn’t found a tag or something else for this case.

An trade Example:
EUR/USD trade with home currency SEK. The split/home currency rate EUR/SEK or USD/SEK is necessary for this trade!
