Just to add my idea:
What I could imagine is a kind of simulation mode for the mount. Based on a start time (date/time) and the target's RA/Dec data, Ekos could calculate the target's trajectory during the night and move the mount as if it were tracking the target (of course without guiding or plate solving). To do this, the orbit data would then have to be converted into control impulses for the mount and the mount would follow the target at a selectable speed. Since the orbits of targets can be very different (e.g. circumpolar or non-circumpolar orbits), it is not possible to estimate how this affects the movement of the telescope with respect to the pier.
