How to prevent route creator straighten turns

Hi. I am new user here, i found this route creator few months ago. I mostly use it for creating gpx routes for indoor cycling app named Biketerra, because it supports own gpx routes.

I noticed that this route planner app shortens turns, so after my route is ready, and i upload downloaded gpx file to Biketerra, route does not look "realistic" on map because of these turns are shortened during this gpx creation.

Is there any way to make it more precise, i mean more accuracy to follow turns?
