Can Teamtreehouse make more code challenges in the tracks, either as courses or a track itself?

I've been following the iOS track with the great teacher Pasan Premaratne, and am halfway through iOS with Swift. I've noticed (and am not sure if other classes are like this) that there are three styles of modules: 1) video lecture 2) code challenge 3) concept quizzes. Number 1 and 3 are great, and as you progress the videos get longer, and so do the quizzes. But I find the most value, and the reason why I love paying monthly for Treehouse is the thought that is in the lessons, especially the code challenge.

Question: Can your team make more code challenges for each lesson module? Or make one full course that holds all code challenges, starting from the beginning of the track until the end?

i.e Swift Basics Code Challenges, Collection & Control Flow Challenges, etc.

I understand if someone says "go start a project and learn by doing" or "go find it elsewhere and practice more yourself". This is both correct, but a lazy answer as I look at Treehouse as a service, and am happy to pay more for the challenges since they're more structured than what you can find on the internet or come up with.

Idea to scale code challenges: Since the community is so strong on Treehouse I'd suggest open sourcing the process of creating these challenges. Possibly with a platform that'll allow for people to create challenges, and for your staff to moderate. This example I've seen done on sites like okCupid in that they allow others to create questions that better their algorithm's matching %, utilizing user generated content to increase participation, and empowering the power users of the platform.
