It seems like it should be an option on Cura 4.4 but I don't see it. If I load the same filament into both materials, it seems there should be a way for the UM5 to auto switch if/when filament runs out mid print. I would love to have this feature.   we have ordered the material handling station but they have not actually released it yet...so I am stuck. We run 2x UM5s nearly 24/7. With the machines not pushing notifications to us that filament ran out, we have to keep a very close eye
