Looking for a way to update the viewport without having to scroll after render in DayPilot Scheduler

Hello,
I'm working on implementing a zoom feature with the angular wrapper of DayPilot Scheduler
The problem I'm facing is when a user changes the zoom level I want to update cellDuration and cellWidth properties while staying centered on the current viewport, so the way I came up with is :
* update cellWidth and/or cellDuration
* store a 'scrollTo' object with current viewport for later usage
* call scheduler.update()
* onAfterRender() => if a "scrollTo" object exists scroll to this object

This results in a flickering and not-so-smooth behavior of double rendering.

In this sample of yours https://themes.daypilot.org/scheduler/create you use the same tactic of storing an object to scroll after rendering and fadeOut/fadeIn before after the render
which is (as far as I understand) a way to avoid the problem I describe here.

I'm looking for a way to postpone rendering , so when scheduler updates itself it would be already at the given "scrollTo" position.
I'm aware of the Scheduler.update({ ...., scrollTo: {}) syntax.
I think what I have in mind is an extra option which could be something like :

DayPilot.Scheduler.scrollTo(date | pixels[, animated[, position]], waitForUpdateCompleted );

And If waitForUpdateCompleted is true, Scheduler would render only once in the correct position.
I hope you get the idea

Thanks for any feedback or a way to solve my issue
