Could I use my own userIDs as a custom props in custom events?

Hi, so I'm thinking about using Plausible self hosted because I think it fits all the analytics requirements that we have and I like the privacy approach.

I understand custom properties can't contain any PII, which is fine. But I'm wondering if I could in theory send as a custom prop the uniqueID which our users have in the DB to some custom event goals.

And If I do, I understand I could get a breakdown of each custom event by user in the dashboard right?
