Button to turn off previous rendered image in VFB?

[Ihno]

Hi,
I´am searching for a button to hide (make it black) the previous render in the VFB while rendering, to see which parts of the image are already done in the current render.
Is there something like this?

I would like to have this dropdown in the VFB to be able to change it while Rendering.
But i think this will help. Thanks!

Such button already exists in the VFB and it's called Clear Image. It doesn't work during the rendering though.

Yes, i know this Button.

My intension was to see which parts are already rerendered and have a Butten which turns off the cross or whatever is set ub to be the overlay.
So i could have both: I could see what is already new and also I could see the difference without any overlay while buckeds gets rendered.

I am rendering a huge still which takes several hours and i do other stuff while rendering it.
When i take a look onto it after some hours, i can´t see what is already rendered and if i set it up to see it. I can´t clearly see the difference while watching the buckets rendering.
But i´ll get it done anyway i just wondered if something like this is possible in the VFB.
This isn´t war-deciding.
