Add Recurring Record in schedule recordings manager

Basically, It's an option when you add a scheduled recordings to repeat the recording "every days" or "every week" or "every days of week".

I'm worked on that with the source 1.1.7 and it's working just fine for a week now (every program that I schedule to repeat is repeating as plan) and I want to summit the code but I don't know how. And I just find out that the branch 1.2 is on the way. Is there a place that explain the way to do that ?
