It would be useful when upgrading to a new manufacturing building if there was some way to transfer all the processes configured in an existing building, maybe by allowing copying the configuration to storage media. It is particularly tedious to copy the production lines of an airport repair shop, which typically have many production lines to cover every type of module.
EDIT: Also useful when you just want to move a building somewhere else.
