I noticed that when a set of custom defined view presets are configured and the zoom feature is enabled, as you move the slider it removes what was configured to what appears to be a set of defaults?
You can see what I mean by going to the live example on this link and moving the zoom slider
https://bryntum.com/docs/scheduler/api/Scheduler/preset/ViewPreset
or by viewing this video
I was hoping that I could leverage the built in slider or even have the zoom programmatically fired from a click of a button or event so that I can zoom in/out of a specific header. My requirements are for example; If I had Quarter, Month and Week as the custom headers and I zoom out I would like to zoom out on the Quarter only since it is the largest view and similarly if I zoom in it would zoom on the Week only. Is this possible?
