Persistent player info such as custom spawn tags

Please correct me if I’m wrong, but currently there isn’t a way to refer to specific players through Condo IO or remember things they’ve done, such as which Custom Spawn Point they’ve reached.

For example, I’d like if once a player reaches a spawn checkpoint and receives that spawn tag, they can quit and rejoin my condo at any point in the future and spawn at that checkpoint each time, basically saving their “progress” in my map. If that’s not doable then a way to refer to specific players (like listing their SteamID64s in the Spawn Tag box, perhaps?) to set their permanent spawn would be handy.

I think this would be useful for more Condo IO-related things than just per-player/saved spawn points, but that’s just one example I have at the moment.
