How do I mark a position in the same place across all tracks?

I'd like to mark a position across all tracks. 
How do I do this?

If I use 'mark' > 'markers' > 'add marker' then a marker gets added, but only on the track that is currently selected. This isn't much use to me.

I want to mark a position in the same place across all of the tracks. Not just one of them.

Thanks.

Praise Bob! Ah, such memories! Those were different times.

I don't think there is a way to do markers on multiple clips at one time. But that would be a cool function to have!

Don't fry with the pig-boys, pull the wool over your own eyes, praise Bob!

you are aware, FCP follows a different concept (magnetic timeline) ? No such thing as 'tracks' …
What do you like to accomplish?

Good mention, Karsten!  And now that you mention it, I've never had need for this, so yes, why would you need markers across all clips in a "stack"?

Don't know what the poster is trying to achieve but I'll do this occasionally to verify visually all 'tracks' have remained synched. It's my way of checking if I've slipped audio or video inadvertently.

I use Compound Clips for that, but yeah, that's something I could see someone using markers for. But since I can link all stems to the exact same spot on the Primary Storyline clip, why bother?
