Are you using IndependentScreens or something?  Having more screens for
multi-head setups is not the default behaviour.

There is screenWorkspace[1] to get the workspace of some monitor, which
could then be used in a manageHook as normal

    -- for monitor 1 (≡ the second one; we are 0-indexed)
    appName =? "my-app" --> maybe mempty doShift =<< liftX (screenWorkspace 1)
