Such questions have already been raised many times in different topics. Many different wishes to have something non-standard in the navigator. For example, it was with the average speed section, the user expressed a desire to turn off the navigator when he visited a gas station and when the navigation would work again, the average speed section was activated, but this is not possible since the section is measured from the start point to the finish point and if the navigator was turned off, then the start point is lost.

Standardly, the navigator with a route that was not completely passed is turned off, after the gas station the navigator turns on and offers to continue the route or cancel it.
