Resume scene / change Target SPP without re-rendering everything

Issue: Resuming a loaded scene (with albedo and normal map rendered) / changing the Target SPP on a completed render does not resume from current SPP. Rather it resets the render progress; Rendering the albedo & normal map and the image again.

Expected behaviour: Without the Desnoiser you can resume a render and/or change the Target SPP without resetting the render progress. Assuming the scene has not been changed.

Work around: Deselect the Denoiser Plugin and bake the render. Manually denoise using previously rendered albedo and normal maps.

(This is just a reminded. No rush)
