Finding a specific restaurant on a route - closest without diverging too much?

Hello,

This is a hard question to phrase. Suppose I'm driving from LA to Vegas - about 250 miles. I have the directions being given to me by the built in app. I'm just leaving LA. I'm hankering for 5 Guys. I have a tight schedule. So I may not necessarily want to find the closest one to where I am at that moment but the closest one to my route - be it 5 miles a head or 200 miles ahead. Is there any way the system can look at my route and say - OK - in 160 miles there is a 5 guys just 1/2 mile off the highway that is on your route?
