Access to the target instrument for cross trade from the APIs

[yfnrcacwvg]

In live mode, with real trade, we can setup cross trade (e.g. ES -> MES). From the API point of view (simplified or core), do we have a way to know the target instrument ?

Please consider implementing this feature.

Please add to the API the possibility to get information on the cross-trading instrument, like alias, tick size, multiplier, etc. Please also document how the orders and executions are handled. I have detected double order IDs and double execution IDs with a ":R+" postfix.
