Is it possible to see all keystores generated?

Is it possible to see what keystores are linked to your master key/mnemonic phrase?

I found this:

"There is a single "master key" (=Mnemonic phrase) which allows the user to attach as many validators to a single withdrawal key as they want.
This way the user can derive all keys from the Mnemonic phrase."

So I understand the Mnemonic phrase attaches all the keys, but is there a public or private way to see all the keys or validators under one "master key" or where would that unique identifier be that links them?
