I'm not really familiar with the Metron so I can't speak to it very well @CardiacTasty, but I can share at a high level that on my own journey here sometimes it's not the modules. It's possible that your rack can do a lot of what you want as is and there's some growing pains there? Certainly that has been the case for me at various points along the way. So I'm curious, what exactly are you finding clunky here? What's not working?
