why cant you do a time trial on unshared quick mode tracks nor save them

That's the stupidest thing ever. Like why cant i do time trials on QM Tracks nor save them? Why is it like this? I don't understand, like there's nothing about the track that makes me unable to save it or do time trials on it. You could just bookmark the URL but i don't feel like doing that. You can do both of those in CM with unshared tracks but not in QM. Fix this IMMEDIATELY because it's literally the stupidest thing ever. Like what were you thinking?

Huh. Never noticed that.
