Flex Duct Patterns are still very locked down and I'm not seeing a way to change/remove existing flex duct patterns from what has historically been available:
Even if we cannot edit the patterns from what is there, or make our own, it would be very helpful to at least allow some of these patterns to be purgeable so that our staff doesn't inadvertently use the wrong flex pattern. It is easy to change them all after the fact, but paring the list down would be great.
