Start and End Point Demo Version (Windows/Spotify)

One Question before I buy the algoriddm DjPro.
I have downloaded the Demo version for Windows PC and I am using mainly spotify.
In the demo version I coudn’t find any option to set permanent “start” and “end” points to a song.
I could set cue points in the demo and also by clicking on the main Set button some kind of “start” point but no “end” point.
Is this possible for the full version (windows/spotify) or not?
This is really important for me if this feature is provided!
