How about this. I just had the idea of putting this into the Turn Sequence of ITL p 101. It is a rough concept that needs some vetting:

(7) Ride-by. Any charging horseman which became adjacent to one single hex figure may continue its charge after its own combat and all other (4) Actions have been done this turn. This additional movement may be up to the full extent of the beast’s MA.

If it comes in contact with another single hex figure this turn, the turn ends with the horseman and opponent figure being adjacent and ready for combat next turn (noting that the horseman, if he survives, may continue his charging as per this Ride-by rule.

In this way the horseman can charge & ride-by and charge some more. If the post Ride-By involves another 'engagement' before the turn ends, then their combat starts off the next turns' action and that horseman can continue his charging.
