Parameter for minimum trade size for a limit order

[phctrade]

Does anyone know if I can enter a minimum trade size on a limit order and what that parameter name is that I need to pass to the either the LimitOrder structure or the ib.placeorder method?

Nothing comes to mind immediately (IBKR only supports full-size FOK orders for options), but if it exists it would be metadata on a special order type from places like these:
