Is there any way to control how lens flares are blended in the post process stack?

For me the lens-flares seem to multiply with exposure and change the exposure of where the lens flare is on screen. When in reality a lens flare should be mixed with the luminance calculated by exposure and other color adjustments and not enhance the final image.
