Joints in template drops

Hello Community,

we are modelling a corridor in Open Rail Designer,

part of the corridor is a concrete slab which is the base layer of this corridor.

There are to be vertical joints seperating the concrete slab into pieces of approx. 10-12 m length (depending on external factors).

I am trying to find a hint whats the best way to implement these joints. I know the stations of the joints btw (Stations of joints are in an excel list).

Thanks in advance and Kind regards
