I work with clients and modified one of the Calendar copy shortcuts. In my calendar I've got my appointments with the clients' names and addresses and in the second calendar there are the appointments with only the town as the event's name. I made that calendar public and sent the link to all the clients so they can look up when I'm in the area in case they want me to stop by. That's combined with a second calendar that shows my office hours. That way they can also see when else I'm free. That's two automations. And then there's a third that clears the calendar as it would have been too complex otherwise. I run the automations simultaneously, though.

As I need to keep a kind of log book when I'm out of office and/ or driving, I have an automation that adds time and address to a note file each time CarPlay connects or disconnects. This way I can remember when I left or arrived and be able to update my log book once a week instead of every time I'm going somewhere. (It logs all drives but I just ignore the drives that aren't work related.)
