There are maneuvers that allow the momentum to transfer they just are not instantaneous.
The faster you want to translate the less momentum you can save. Mind you this is for pure translation only you can save a marginal amount of momentum by translating and rotating at the same time.

Using banked turns on a swerve drive is best as it allows for the most momentum saved over instantaneous turns.
