Complex Position names can be flipped on the Classic TWS Portfolio tab or the Mosaic Portfolio Watchlist automatically based on default parameters that support the use of canonical names. Once the combo name is flipped in the Desktop TWS, the combo name will be updated in your IBKR Mobile Watchlist/Portfolio as well.
To manually flip the combo name, right-click on the combo position line and select "Flip Combo to…." (you might have to expand the menu by clicking on the small circle/arrow at the bottom). The description, position and the Bid/Ask prices will then flip on your data row.
To find out more about the single-line display of complex positions, see the TWS Users' Guide and the Complex Positions Summary page of the Reporting Guide.
