Method of starting a new PhD trajectory after a completed previous trajectory

Explanation: 
Sometimes a PhD trajectory is terminated early and the PhD student in question continues with a new PhD trajectory at a later date with a different subject, and often with a different first supervisor.
Which steps in Hora Finita should then be carried out by the GS?

Step1

1. create e-number for the PhD student with the data from the p-number
2. link e-number to the previous, terminated trajectory registration (if any)
3. link e-number to the previous, terminated PhD trajectory

Step 2

1. start new trajectory registration with the PhD student's p-number (only for GSMS)
2. start new PhD  trajectory registration with the PhD student's p-number

In this way, the previous PhD trajectory is kept linked to the e-number (historical data) and a completely new trajectory is started in Hora Finita, linked to the p-number. 
When logging in, there is no longer any reference to the old trajectory registration or the old PhD trajectory.
This way, there is no confusion between the old and new information.
