URL for parts of a longer route

At http://ebike.bitplan.com we systematically document our bike tours. Each route leg has it's own page see e.g. http://ebike.bitplan.com/index.php/GB2019
For older tours we now are not planning daily but documenting the whole tour as just one route e.g. https://cycle.travel/map/journey/148974 - now it would be great if we could still link each leg-page in our wiki with just the relevant part of the tour. Is there some extra parameters that will allow that e.g. https://cycle.travel/map/journey/148974/via/1-7 or https://cycle.travel/map/journey/148974?viastart=1&viaend=7

If this is not available yet we'd love to get this feature.

Cheers
