Is there any option to set size while exporting?

I could not find the option to set the size while exporting. Also show the estimated file size.

@Jayanta-Das No, the size is calculated automatically using the resolution set when exporting (for images).

I add this to the feature request lists, and will do it as soon as possible, as this one is indeed something that is needed.
