Channels Collections in m3u

Feature request

When generating a m3u file from Channels DVR:

http://x.x.x.x:8089/devices/ANY/channels.m3u

For the item "group-title" have Channels DVR replace "HD", "Favorites", etc and use the Collections name(s) for the group title instead?

If so, while in the code, have the "tvg-chno" represent the Collection and channel order. For example:
1-News
2-Movies

In the m3u file for tvg-chno=101 which would represent Collection News (1) and 01 the first channel in the collection.
tvg-chno=201 would represent Collection Movies (2) and 01 being the first channel in the collection.

How do you list multiple groups in m3u format ?

I've seen multiple groups in m3u. I have no idea if that actually works. Can it just be the Collection name?

@tmm1 - has there been any additional thought about including this? having a channel collection automatically generated based on the m3u group-title tag would be useful
