It's a few years since I had a trial subscription, but I'm pretty sure that Carista will do it. Things may have changed but it used be designed so that the free trial version would show you what options it could change - though of course you had to upgrade to the paid-for version before it would actually allow you to do it.
Yep i think Triffic is correct .
I bought a carista earlier in the year and i'm pretty sure this is one of the options it gave you.
When you buy it you get a months free trial but have to sign up to a yearly subscription before it works ....as long as you cancel it before the end of your free month you dont actually pay for the year .
