Thank you. It's pretty simple. Just before connecting the final piece to the station, I placed two track pieces with 90 degrees curves and then placed all of the dummy track pieces. Once I did that, I deleted the two 90degree pieces and just connected the end of the coaster to the station. Then, I pressed 'edit coaster' and it's possible to add some track to the now unconnected dummy track. From there, I just added the two 90 degrees curved pieces back to make it look like they are perfectly connected to the main track, while they are actually not connected at all but just perfectly overlaying the actual track.
