How to contribute faster to Apple Maps

Hello everyone,

I live in Brazil, and Apple Maps, unfortunately, is not reliable here. Most stores don't appear in the map, streets have outdated names, and worse: it shows routes that do not exist.

I am aware that it's possible to send suggestions via the Maps app – though they take too much time to be processed and are often denied.

I'd like to know, please, if there's a volunteer program to help make Apple Maps better in a more appropriate way. Suggesting something via the app itself is good enough when it's a small change, to fix an ocasional problem – but it doesn't work when one wants to help with a considerable high amount of changes.

Better yet if there are openings for this.
