Can't see musical or time base column in Pool

I’m trying to select many audio tracks in the pool and make them all “musical” timebase so I can change the tempo of my project. But I can’t seem to see where to change this in the pool. Should there be a column? It’s very late here, but what am I missing?

It’s hidden right now, just switch it on:

in the Pool window click on “View/Attributes” and tick “Musical Mode”.

Thank you!
