Swiss scenic train reservations

I will be going to Switzerland in June and recently purchased a Swiss Travel Pass primarily for rail travel. I understand it is necessary to reserve seats on the on the scenic tourist trains such as the Gotthard Panoramic Express, Bernina Express etc. Can anyone direct me to a website where I can make seat reservations using my Swiss Travel Pass without buying a separate ticket. Every Google search site I've tried seems to be a dysfunctional deadend.
