End Condition Targeting a Feature Definition Both Horizontal and Vertical

I have a template that has an end condition on the left and the right. This particular end condition targets a specific feature definition both horizontally and vertically. The issue is that if I have a targeted feature on only one side of the road, both end conditions see this feature and they both connect to it ( so I have errant features crossing my road). I would prefer to have the end condition look "directionally" much like a horizontal feature constraint which "looks" out based on the range applied. Am I missing a setting or is this not possible. Obviously, I can make a left and right specific feature definition but that seems less elegant. 

Thanks,

Terry
