A coherent receiver s like a FM radio, you can tune what it listens so. So if you send it all waves the receiver can decide what to listen to.
But you'd never send it all the waves anyway, that's far too much loss across the band. ROADMs already solve this problem, and are available at the module level (how practically available and usable I've no idea, never needed to try).
