Looks like this has been updated and is working well!

Just wanted to share a test video of the new update to @mikewax "AAF Helpers"...

He let me know a new update was coming and I got it working well. Here is a video demonstration i made for him but in case it is helpful to others you can watch. Just make sure your isos have track/channel meta data ie "Boom, Lav, Plant, Character Name, etc etc"... The video starts with a bit of troubleshooting but it successfully runs for me now. Thanks Mike!
