Reverb question

hey all

a question that's been boggin' me since a while
picture a wide forest area that extends both left and right and say I have an audio source on the left of the screen, a guy that's hammering steel..
Is it possible to apply a reverb filter that the more I move away from the source the more reverb I hear (as it would happen naturally)

so far I managed to apply Unity's inbuilt reverb the other way 'round only .. the closer you are the more reverb you hear...

know if it's possible?...
