Permanent ID and connections between items


I’m developing a Kirby instance where I regularly encounter a problem: maintaining links and connections between fields defined in the data model.
For example: I have a event programm space where I can define conferences and associate speakers from a separate field (entity). When I change the name of a speaker, it breaks the connection with the linked conferences.
It’s a real pain, because it requires constant vigilance in site administration. Is there a way to prevent this in the way I design Kirby’s data and field model?


Could you please elaborate a bit more and provide the relevant blueprints where you establish your connections. I don’t really understand the problem or what exactly is happening.
