Dear @JKM ,
Sorry for the late answer. Yes, there are several ways. The first is to create a Point Sensor: after dragging and dropping the axonal entity, a list containing the name of all the sections will appear. E.g. for a myelinated SENN model, the list will show names such as node1[0],internode1[0],node1[1],internode1[1]...
A second way, via Python is to run the following code that provide a list containing all the section names:
import s4l_v1 as s4l
sim=s4l.document.AllSimulations[simulationname]
sections=sim.GetSectionNames()
