Asynchronous trade access for party members

Being in a party you can not access your personal asynchronous trade merchant from another persons hideout. Its very inconvenient to need to leave the hideout that you are conducting your maps in to go to your own hideout and put up items for trade in the asynchronous trade merchant then come back to your party location to continue doing mapping. It would be so much better if this could be accessed from a hideout other than your own.
