Working As Designed: How to change default car for fill-up in GasTracker+

[idburns]

I just downloaded the GasTracker+ app under iOS, how do I change the default car being filled up?

When I click the round, orange button on the main screen of the app to add a fill up it defaults to my GTI. I want it to default to my STi.

How do I change this?

I tried changing the order of the cars in the app, but that didn't work and there doesn't appear to be a setting anywhere to change the default car.

thanks!
