[Feature]: Add "scheduler" param to TransformWithInlineUpdate

[giard-alexandre]

Describe the functionality desired 🐞

Potential feature suggestion to optimize TransformWithInlineUpdate.

This scheduler could be used for running updateAction, making it possible to create the objects on a background thread while ensuring that updates happen on the desired thread (usually the UI thread in WPF style apps).

The steps the functionality will provide

N/A

Considerations

I use ObserveOn(scheduler) at the moment but this makes creation also run off main thread.
