Sometimes the best detours—in life and on the road—are unplanned. But for those times when you know exactly where you're going, Lyft is rolling out a new feature to make it easier for your driver to take you there.

The ability to add an extra stop to Lyft rides will soon be coming to the app. You'll be able to add or remove a stop and your route will instantly update. That means you'll never again have to explain to your driver how to get to the dry cleaners on the way to work, for instance.

The process will work much like the recently-added multiple destination feature in the Google Maps mobile app. You tap the "add" icon to enter your drop-off location, then request your ride. An "add destination" field will then appear, so your driver knows where to go first.

A Lyft spokesperson explained that pricing for multiple destination trips entered into the app will work the same as it does currently. Adding a stop doesn't cost any additional fees, but you'll be charged for however long the stop takes based on the per-minute rate for your city.

It's not clear when the feature will be rolling out and if the option will be phased in for certain cities or made available all at once. A Lyft blog post said only that the feature is coming soon, and the spokesperson declined to comment further.

Although adding a stop to a Lyft ride is already possible if you ask your driver, making the process simpler is likely to please Lyft regulars, many of whom use the service as an alternative to public transportation. Boosting its app's ease of use is also key for Lyft as it faces intense competition from both archrival Uber, which doesn't have a multiple destinations option, as well as city-specific newcomers like New York City's Juno.
