Edit corridor and for example add pedestrian crossing parametric

I got a question from a colleague if it was possible to for example add pedestrian crossing, widening for bus stops and qul de sac based on a parameters in a corridor without need of redesign the corridor or adding extra subassemblies (maybe not possible for the bus stop)
The picture is from one webinar with @Paolo_Emilio_Serra1
[Webinar] Infrastructure Design Automation with Dynamo for Civil 3D - YouTube
If I understood what they said on the webinar about Civil 3D 2020, then it was only possible to to this on the corridor surface but I wonder if it’s possible in Civil 3D 2021 or 2022?
