Adding a Person with a specific gait motion and a person who is a white cane user in Carla

[rayruchira]

I am working on simulating diverse pedestrian behaviours in CARLA. I want to add a pedestrian with a specific gait pattern (e.g., limping or an asymmetric walking style). What would be the best approach to modify an existing animation or import a new one into CARLA?
I also need to introduce a pedestrian pushing a stroller and another using a white cane. How can I do this?
