how to set distance on redfin and zillow for comps

[Yusuf Sarii]

im trying to run comps on mainly redfin and sometimes zillow  but the one thing i dont see is to set the distance from a specific property to find comps in the same are for example properties sold within a 0.5 mile radius from the property 

propstream has this feature but is there any way to do this on redfin or is there a workaround because all i can do is zoom in and out of the map and i cant set a specific number ie(0.5,0.25,1) miles away from property to find comparables
