I dont recommend to use ORCA as a booster because when you warp or dock, you switch off links and such parameters as mining amount and laser optimal range will change. Bot will not understand when the asteroid should pop and as a result may try to cut asteroid too early, then mine it again for the next full cycle. Booster should stay at savespot all the time. If you need remote hauler, better to use industrial ship to haul your ore.
If you want to use ORCA to haul your ore you may try
custom algorithm for this.
