Subfolder in Swagger UI

[LLCcom]

The problem is that within one characterization there might be many api endpoints making the list too long to read. Move part of them into another characterizaion is OK. But in swagger documentation it becomes a peer rather then a nested folded subfolder. I want to preserve the hierarchical order for example:

in original swagger documentation:
person:
   -------[get]person/pid
   -------[get]person/device
   -------[post]person/device
   --------...... many other endpoints

I wish I could make it clearer and preserve the hierarchical structure like this:
person:
   -------[get]person/pid
   -------device:
         -------[post]person/device
         -------[get]person/device
   --------...... many other endpoints
